3670 is a Korean movie about a gay man who defected from North Korea. The main character risked everything to escape his old country and start a new life. Since then, he has struggled to make social connections. His shy personality and cultural differences make it harder for him to fit in. During a mixer, the protagonist meets someone special. His new friend helps him come out of his shell and build relationships with others.
I highly recommend 3670 as a movie. The unique experience of a gay North Korean defector is something I've never seen explored in LGBTQ+ cinema before. There are many emotional moments, especially when the film explores the protagonist's loneliness. I started off rooting for the couple, and I found them compelling even when their relationship got messy. The acting is impressive, helping me feel even more immersed in this complex story.

Plot

Cheol Jun used to live in North Korea. He left his parents and his whole world behind to flee the country. Now, he lives alone in South Korea, where his only relative in the area is a distant aunt. Cheol Jun is trying to make ends meet with a government scholarship and a part-time job at a convenience store. His social life consists of attending church and meeting up with other refugees. For his long-term goals, Cheol Jun hopes to apply to a university and get accepted.
Cheol Jun spends most of his time with Hak Min and Jeong Hak, two other guys who defected from the North. Out of the group, Hak Min is financially struggling. He's desperate to save enough money to get his parents across the border, so he's constantly short on cash. Cheol Jun is happy to lend him money. To settle the score, Hak Min decides to play matchmaker. He wants to set Cheol Jun up with Ji Ye, a girl from their class. Cheol Jun isn't actually interested in her, or any woman for that matter. He's attracted to men, but that's a side of himself he keeps hidden from his friends.
Cheol Jun has been using apps to meet guys, but it's always the same story. They're just looking for something quick and disappear as soon as it's over. Tired of feeling lonely, Cheol Jun attends a mixer for gay men. He's awkward and out of his element, but the other guys seem curious about his North Korean background. When the night winds down, everyone is supposed to exchange numbers with the people they liked. Cheol Jun leaves his info for Hyeon Taek, a handsome guy who sat across from him. Yet, no one at the mixer asked for Cheol Jun's number.
The next day, Cheol Jun is working at the convenience store when a customer walks. It's Yeong Jun, one of the guys from the mixer. He recognizes Cheol Jun and seems happy that they live near each other. After work, Yeong Jun invites Cheol Jun to talk more. Away from the pressure of the mixer, the conversation gets more personal. Cheol Jun opens up about what it was like back home. He explains that being openly gay in North Korea was unthinkable. However, Cheol Jun admits he did discreetly experiment with a few guys behind closed doors.
Yeong Jun brings Cheol Jun along to meet his inner circle at a gay karaoke bar. It's a small, low-key gathering. The group is nice enough, asking Cheol Jun questions to know him better. As the night goes on, Cheol Jun's shyness kicks in. He fades into the background. Meanwhile, Yeong Jun is totally in his element. He talks to everyone and even hops on stage to sing. Even though Cheol Jun is struggling to stay social, Yeong Jun doesn't give up on him. He keeps bringing his new friend to events, patiently nudging him out of his shell.

3670 Review
Review
Movie Review Score: 8.6

3670 is a very unique movie with a meaningful story. I promise you, there aren't many LGBTQ+ films about defectors from North Korea! The main character, Cheol Jun, risked his life to flee an authoritarian regime. For viewers in free countries, his journey is unlike anything most of us will ever experience. Think about the sacrifices he made or the courage it took to escape. Wow, his hardships are so much bigger than ours! 3670 offers such an interesting perspective, showing what it's like to be gay and living in exile.
Even though Cheol Jun's situation seems extraordinary, his struggles are relatable. At first, he felt like an outsider in South Korean society. Cheol Jun found the gay community, yet he still can't connect with them. His inability to fit in with people similar to him might be one of the loneliest feelings ever… 😢 Argh! My heart breaks for Cheol Jun in those scenes where he's shy and awkward. I've been there, I know how it feels, and many of you will understand him too. The movie is excellent at making us care about the protagonist. We grow attached to this underdog and get emotional over his painful moments.
Yeong Jun swoops in like a fairy godmother to rescue Cheol Jun from his isolation. He's exactly the kind of friend Cheol Jun needs, pulling him into a social circle and helping him open up around others. Their scenes together are just like Yeong Jun's bubbly personality. He makes every moment feel playful and casual. As we watch these two grow closer and get along so well, it's easy to ship them as a couple. Many BL fans are probably cheering for them. Confess already! Make your relationship official! They're one honest conversation away from being boyfriends.
What makes 3670 a complex movie is that it won't give us the easy, feel-good love story we want. Instead, we watch the couple's deep-rooted insecurities wreck their relationship. At times, it's so frigging frustrating to watch! I wanna scream at these two dummies to sort out their damn issues! Their conflict takes over the second half of the film. The storyline is actually well-written and tackles meaningful themes. Yet, it also kills my enthusiasm for the romance. The more they fight, the less I'm shipping them. By the end, I'm not even sure if I want them together anymore.
Quite impressively, Cheol Jun's actor (Cho You Hyun) has won a critic's award for his debut in 3670. Yeah, he's really convincing in his role. He captures the character's vulnerability and social awkwardness, but you still see an underlying strength in him. Also, can we talk about when he takes his shirt off? Those abs are a total revelation! His co-star (Kim Hyun Mok) shines as Yeong Jun. He can be incredibly charming during the movie's lighthearted moments. And he's even better in the emotional scenes, handling all the heavy drama like a seasoned pro.
3670 has a bittersweet ending. Even though the romance is left unresolved, I love Cheol Jun's character growth. The final scenes show how much he has changed, and it makes me proud of him. Overall, I adore this movie for telling a powerful LGBTQ+ story with a complex protagonist and his beautifully written journey. The emotional moments got to me. The thoughtful themes stuck with me. And the unique North Korean perspective is something I've never seen in a gay film before. Everything comes together perfectly to make 3670 feel like a special piece of cinema.

Natural acting

Realistic artistry
The movie has solid production values. It keeps things simple and low-key, opting for a realistic atmosphere rather than an overly polished look. But I wish the kissing scene had better lighting.

3670 Movie Explained
Analysis
What is 3670?

For most of us, 3670 seems like a mystery. We don't know what it means before this movie. The film reveals it's like gay lingo. 3670 is a secret code that men use to meet up in a specific part of the city. Each number stands for a different instruction. The 3 is for the train station number (Station #3), the 6 is for the exit number (Exit #6), and the 7 means the meeting time (7 PM). The last number, 0, counts how many people are participating. If you're the first person to join, you say 1 (3671). If you're the second, you say 2 (3672).
According to the secret code, 3670 means no one is showing up for the meeting. Sorry, there's a big fat zero in attendance! It's a very lonely number, which mirrors how Cheol Jun feels at the start of the movie. Our protagonist has zero gay friends, zero family nearby, and feels like he has zero importance in this foreign city. At the gay mixer, Cheol Jun realizes how unpopular he is. While the others seem interested in his background as a North Korean refugee, no one cares enough to leave their contact info. They see him as the quiet guy who doesn't fit in. Around the local gay community, Cheol Jun feels like a total 3670.
Loneliness

As a gay North Korean refugee, there are multiple layers to Cheol Jun's loneliness. The first layer is being a North Korean in South Korea. Even though they speak the same language, the cultural gap is massive. Cheol Jun has very different life experiences from South Koreans, so he can't relate to their normal conversations. Take karaoke songs, for example. Cheol Jun has missed out on years of mainstream music. Whenever he's asked to sing, it makes him feel self-conscious about being an outsider in a foreign country.
The second layer is being gay among his North Korean friends. Cheol Jun has a few friends. Straight friends from church. These are his fellow North Korean defectors who understand what he went through as a refugee. Their small group sticks close together, but Cheol Jun must hide his sexuality from them. Church communities aren't typically accepting of LGBTQ+ people, and his friends come from a traditional background. Cheol Jun can't talk to them about the guys he likes. Even when he's with his friends, he's still kind of alone. Cheol Jun is surrounded by people who only know half of who he actually is.
The third layer is losing his family forever. When Cheol Jun escaped, he had to leave without his parents. He can't call them. He can't visit them. He doesn't even know if they're okay. That connection is gone permanently. Throughout the movie, the storyteller constantly reminds us of Cheol Jun's homesickness. We see him staring at a location pin on Google Maps, where his old house used to be. Most people can't imagine cutting off their entire family just to be free. Cheol Jun carries that loss every single day, and it's a loneliness that never goes away.
Exile

Cheol Jun's experiences are even more poignant when you consider how much he sacrificed to be here. Firstly, he risked his life. Escaping North Korea isn't like moving to a new country. It's dangerous and illegal. If you get caught, you're thrown into a prison camp or worse. Cheol Jun had to sneak out, knowing that one wrong move could get him killed. The scene where he describes his escape is harrowing. Hearing his whole story makes us realize how easily he could've died. The fact that he's here now, still standing, feels like a miracle.
Secondly, Cheol Jun must leave his parents behind. He couldn't convince them to defect with him. They considered North Korea their home, despite everything. In one of the movie's darkest scenes, Cheol Jun holds a funeral for his parents at his aunt's home. That moment hits us hard because the gravity of the situation sinks in. Cheol Jun is mourning his family because he won't see them again, almost like they died the moment he left home. The reality is that Cheol Jun will never arrange a proper funeral for his parents. He can't honour them the way a son should. This makeshift ceremony is all he gets…
If Cheol Jun regrets leaving or misses home, too bad. His exile is forever. There's no "what if I made a mistake" option. Even when good things happen, there's always that underlying sadness that his family isn't there to share it. His parents will never know how their son is doing or if leaving home was worth it. Plus, the fact that Cheol Jun is gay adds an extra layer of tragedy to his situation. Cheol Jun's aunt says his parents want him to settle down, find a wife, and have kids. But Cheol Jun can't fulfill that wish. He carries this guilt without ever finding peace with it.
Yeong Jun

After his unsuccessful night at the mixer, life was looking bleak for Cheol Jun. He hadn't made any new friends. None of the guys seemed romantically interested in him. It's such a lonely feeling to be surrounded by other gay men, just like himself, yet he can't connect with them. At least when you're alone, you can tell yourself that things would change once you found the right people. But when you've met them and you still don't fit in? It crushes your hope that things will get better. You're destined to be an outsider forever.
Just when Cheol Jun walks away from the gay community feeling lonelier than ever, Yeong Jun shows up. Like a gay fairy godmother, Yeong Jun is here to save Cheol Jun. He waves his magic wand (so to speak) and suddenly Cheol Jun has access to a whole social world he couldn't enter before. As the resident social butterfly, Yeong Jun invites Cheol Jun to hang out and introduces him to his friends. Even though Cheol Jun is still shy in big groups, Yeong Jun always includes him in these events. With a good buddy by his side, Cheol Jun eventually feels comfortable enough to open up around others.
When I first watched 3670, I didn't recognize Yeong Jun. Who's this random character? I don't remember seeing this guy at the mixer! After rewatching the scene, I realize the movie hid him on purpose. Yeong Jun was there the whole time, just blurred out or tucked away in the background. At the time, Cheol Jun was focused on Hyeon Taek, the stud sitting across from him. As viewers, we end up having the same tunnel vision. Cheol Jun doesn't recognize Yeong Jun until they meet later at the convenience store. Despite his importance, Yeong Jun was overlooked at first.
Feelings

As they spend time together, Cheol Jun catches feelings for Yeong Jun. It's easy to see why, because his friend has many attractive qualities. Yeong Jun's warm, bubbly personality draws everyone to him. He's charming and knows how to talk to people, which is basically a superpower to someone like Cheol Jun who struggles with every word. Yeong Jun is also witty, making Cheol Jun laugh when his life has been so serious. More than anything, Yeong Jun is kind. He goes out of his way to ensure Cheol Jun always feels welcome in the group.
Most of all, Yeong Jun makes Cheol Jun feel so special in a way that nobody else has. Yeong Jun is the first person in the gay community to actually notice him. The first person to be nice to him. The first person to compliment his looks and admire his work ethic. After feeling invisible for so long, this type of recognition means everything to Cheol Jun. Having someone finally see his worth changes how he thinks about himself. It proves that Cheol Jun isn't unlovable or unwanted like he feared. Cheol Jun can feel more confident because Yeong Jun believes in him.
At first, Cheol Jun still kept his guard up. Even though they're becoming fast friends, he's protective of his private life. He wouldn't let Yeong Jun go to church with him. Religion is sacred for Cheol Jun, so he may have wanted to keep his faith separate from his gay lifestyle. As his feelings grow stronger, Cheol Jun changes his mind. He invites Yeong Jun to come watch him give a big speech. This is a huge deal! It's the equivalent of saying, "I trust you enough to bring you into my inner world." It shows that Yeong Jun has become an important part of Cheol Jun's life.
Insecurities

Despite his many attractive qualities, Yeong Jun is deeply insecure. He has a bad habit of comparing himself to others. We see it during the birthday party. Even though his gift seems perfectly fine, he gets embarrassed and hides it. Yeong Jun assumes it isn't valuable enough compared to what other guests bought. He does the same thing in multiple areas of his life. Yeong Jun measures himself by how he stacks up against other people, and he always feels inferior in his own mind.
When it comes to his looks, Yeong Jun sees himself as ugly. The other gay guys have all friend-zoned him. They may think of him as the life of the party, but not as a desirable romantic partner. His personal achievements are another sore spot. Yeong Jun's university application got swiftly rejected, making him feel like a failure. On top of that, his financial status bothers him. As an adult, he's still dependent on his parents for money. When everyone around him seems to be doing better, earning more, and achieving more, Yeong Jun feels woefully inadequate.
These insecurities poison his relationship with Cheol Jun. Even though Cheol Jun likes him romantically, Yeong Jun doesn't believe it. He has already convinced himself that he isn't good enough. Not hot enough. Not successful enough. Yeong Jun keeps waiting for Cheol Jun to realize he can find a better boyfriend and leave him. His lack of self-worth becomes a self-fulfilling prophecy. Yeong Jun pushes away a promising romance because he can't accept that someone might want him exactly as he is.
Baby duck

At the gay club, the crowd goes wild for Cheol Jun and his muscular body. For once, he has no trouble fitting in. The hot dudes, especially Hyeon Taek, are suddenly obsessed with him. Cheol Jun and Hyeon Taek head into a private backroom with all the other couples. They start making out and getting frisky. But then, Cheol Jun stops midway. Surprisingly, he goes back to join Yeong Jun on the dance floor. He'd rather be by his friend's side than hook up with an attractive guy. Cheol Jun has made his loyalties clear.
Feeling insecure, Yeong Jun tells his friend to go back to the hook-up. Be with the hot people, not him. Yeong Jun shares his theory that Cheol Jun is like a baby duck. These baby ducks attach themselves to the first thing they see after hatching, even if it's not their real mom. Yeong Jun believes Cheol Jun is doing the same thing. Cheol Jun only likes him because Yeong Jun was his first gay friend. Once Cheol Jun gains more experience and meets other guys, these feelings will fade. He'll move on and find a more attractive boyfriend than Yeong Jun.
Yet, Cheol Jun rejects this theory. If it were true, he would have stayed in that backroom with Hyeon Taek, taking this movie to an 18+ territory. But he didn't. Cheol Jun picked Yeong Jun. From the start, Cheol Jun doesn't match the stereotype of a shallow gay guy who only goes for looks. Based on his history as a North Korean refugee, his priorities are different. Cheol Jun values an emotional bond over a physical attraction. He's looking for loyalty and kindness. Cheol Jun genuinely wants Yeong Jun, someone who was there for him before he had anything to offer.
Rejection

Sadly, Yeong Jun's insecurities strike again. The couple's first meeting at the mixer comes back to haunt them. That night, Cheol Jun left behind his contact info for Hyeon Taek. After Yeong Jun finds out, he feels like a backup option. A sloppy second. He's basically the consolation prize since Hyeon Taek wasn't available. It's also a sensitive time for Yeong Jun, whose university application was recently rejected. Now, realizing he wasn't Cheol Jun's first choice in romance? It's like getting rejected twice.
The truth is that Cheol Jun did overlook Yeong Jun at the mixer. They didn't mingle much. They sat far from each other. Cheol Jun was also dealing with his own social awkwardness, which made him feel overwhelmed. Picking Hyeon Taek wasn't a deep choice. This nice-looking guy asked him a few personal questions, and that was enough. When Cheol Jun tries to explain his reasoning, it triggers another insecurity in Yeong Jun. Being unmemorable is one of Yeong Jun's fears. He has always felt like a background character in someone else's story, so this destroys his self-worth even more.
Yeong Jun saw Cheol Jun at the mixer when no one else did. He reached out first at the convenience store. He invited this quiet loner to hang out. Every step of their relationship happened because Yeong Jun has always prioritized Cheol Jun. But Cheol Jun didn't choose him first, and that triggers Yeong Jun's insecurities. He poured his heart into making his friend feel special. And what did he get in return? The painful truth that he was never special to Cheol Jun from the start. Yeong Jun is embarrassed about liking a guy who didn't want him or even notice him at first.
Pity

Cheol Jun never meant to hurt his friend. Even if he had an early crush on Hyeon Taek, his feelings have shifted since then. Now, he cares deeply about Yeong Jun, and that's what matters most. Yeong Jun's anger is unjustified, stemming from his own insecurities. It's a shame he focuses on a moment of rejection and not the relationship they built. Due to his low self-esteem, Yeong Jun has an easier time believing in the worst scenario. He thinks Cheol Jun finds him undesirable because Yeong Jun feels that way about himself.
Since Yeong Jun's feelings are hurt, he decides to lash out. Yeong Jun jokes that he only became friends with Cheol Jun out of pity. It's a really cruel statement. It's probably the meanest thing he has said in the entire movie. In his mind, making fun of Cheol Jun creates an emotional distance. If he can frame their relationship as something shallow, then the rejection can't hurt him as badly. Yeong Jun wants to pretend the bond was never real. Dismissing the relationship feels safer than admitting how much it meant to him.
Unfortunately, Cheol Jun overheard his comment. The poor guy already feels alone in the world. His life is very fragile. When Yeong Jun became one of his few close friends, Cheol Jun truly cherished their bond. He's grateful to find a genuine companion, or at least that's what he thought. Oh, it must be soul-crushing to hear that the relationship was fake! It destroys his trust in other people's kindness toward him. My heart breaks for Cheol Jun. 😢 After their tense confrontation, these two have basically ruined their friendship. What a shame, what a shame…
