Happy Ending – Series Review & Episode Guide

Happy Ending is a Korean BL drama about two high school friends and their secret crush.

Happy Ending is a Korean BL series about two high school students with ambiguous feelings for each other. The main character is an adult reminiscing about his teenage experiences. Years ago, he used to have a secret crush on his best friend. They enjoyed each other's companionship. Yet, he struggled to confess and only dared to confide in his diary. As time passed, the protagonist grew tormented over his unspoken love.

The two leads of Happy Ending make a cute couple. They capture the feelings of secret longing and emotional torment in a teenage romance. However, the twenty-minute series is too short. Each episode seems empty, underwhelming me due to the lack of content. The plot doesn't flesh out the characters vividly outside of their secret crush. It feels more like a prologue than a complete love story.

High school romance


Happy Ending is a nice & heartwarming drama.


Hyun and Dongho stare into each other's eyes.

Hyun works at a bookshop. One day, he stumbles upon the diary from his teenage years. This memory evokes his memories. He starts reminiscing about his experiences in 2008. Hyun used to be a high school student and best friends with Dongho. The two teens always hang out together, even outside of school. Hyun has developed a secret crush on Dongho. However, Hyun is nervous about confessing these feelings to his friend.

Hyun likes to write. He records his inner thoughts about Dongho in his diary. He'd compose many lyrical passages about his unrequited love with schmaltzy lines like "Your smile makes my heart flutter." Dongho is often curious about his friend's private entries. One time, Dongho snatched the diary and almost read the content. Hyun panics and retrieves the stolen material just in time. Hyun is too afraid to express his secret crush. He doesn't know whether Dongho feels the same way about him.

Happy Ending Review


Drama Review Score: 6.6

Hyun and Dongho have an intimate moment at night.

Happy Ending is a twenty-minute teenage love story divided into three parts. After each episode, I have the same thought: "It's not enough." This series seems too short, limiting the potential to tell a comprehensive narrative. A few quick scenes later, the drama has finished before the couple's romance develops meaningfully. Happy Ending suffers from brevity and doesn't build the momentum to resonate impactfully. I need more time for the emotions to sink in.

Another issue with Happy Ending is that it lacks content. Some short BL dramas compensate for their length by including many details in the scenes. There are strategies to establish the plot quickly, from dialogue to visual cues. It's possible to create a complex narrative in a limited time frame. Yet, this series feels empty. I know little about the protagonists besides their secret crush. The story doesn't define their personalities, backgrounds, or anything else outside of romance. Who are Hyun and Dongho? Both are missing the nuances that would flesh out their characterizations.

Happy Ending depicts a teenage crush authentically. Hyun experiences a range of feelings around Dongho. He blushes at their physical contact, acts nervous when near each other, and feels tormented by his friend's indifference. Each scene is emotionally charged, immersing the audience in the ups and downs of his journey. Hyun's struggles over unrequited love are relatable. You'll root for this sympathetic protagonist to have a successful confession. You'll also feel sorry for him when he succumbs to insecurity. Hyun's vulnerability makes this romance compelling.

Hyun's diary provides insights into his feelings. He recites sad, lyrical quotes that describe his unrequited love. A few lines strike a chord with me due to the poignant messages. Other passages seem overemotional, like the ramblings of a melodramatic teenager. Our protagonist speaks with the solemness of a Shakespearean soliloquy. "Alas, my love for thee shall ache for eternity!" Despite Hyun's attraction, the story dwells on his secret longing. I don't sense romantic sparks between the couple. Most scenes resemble brotherly camaraderie rather than passionate intimacy.

You may recognize Dongho's actor (Kim Seong Hyuk) from his previous series, Choco Milk Shake. Once again, this vivacious star sparkles on screen. Every time Dongho smiles radiantly, you understand why Hyun has a crush on him. With that said, he has limited material to work with. The small handful of scenes don't demand much emotional range from him. The other lead (Park Jun Mook) seems genuine. His sensitive performance leaves a positive impression on me. Also, he makes a cute pairing with his costar. Aesthetically, this BL couple looks well-matched. 

As foreshadowed by the title, Happy Ending concludes positively. The final scene is meant to be optimistic. However, the last episode frustrates me since the narrative finishes just as it's about to get interesting. Finally, there's a confrontation! Except two minutes later, it's already over. I also want to see more relationship moments instead of only focusing on the secret crush. Overall, Happy Ending doesn't feel like a complete series. It may be enjoyable as a twenty-minute prologue attached to a bigger love story. Yet, it sorely lacks content as a standalone drama.


Lacklustre story

Happy Ending underwhelms me because it lacks content. The story is too short and doesn't develop substantially. Both protagonists are vaguely defined without much characterization.

Emotional romance

This series depicts a teenage crush authentically, capturing all the tormented emotions of unrequited love. However, it focuses on secret longing over intimate exchanges between the couple.

Sincere acting

Despite the limited material, Dongho's actor (Kim Seong Hyuk) is a vibrant lead who looks dreamy on screen. His costar (Park Jun Mook) delivers a sincere and sensitive performance.

Happy ending

Happy Ending finishes positively. The last episode includes an emotional climax where Hyun & Dongho confront their feelings. The relationship drama wraps up quickly instead of exploring it in depth.

Poignant artistry

The production values look okay, albeit slightly unremarkable. Hyun often recites sad, lyrical quotes about unrequited love. Some lines are poignant, while others seem melodramatic.


Happy Ending captures the authentic feelings of a teenage crush, which both leads portray sincerely. Yet, the series doesn't resonate impactfully due to its short length and lack of content.

Episode Reviews

Episode 1

This first episode is so short! I hope the others are longer, but I doubt it. I'll need to see more before I can comment. However, the actors look good together. They make a cute pairing.

Episode 2

I like the friend's comment about the dog. It's a cheeky reference to Choco Milk Shake, which Dongho's actor starred in. So far, the storyline follows a predictable love story trajectory.

Episode 3

"The words I've held back keep stabbing my heart." That's a nice line. The confession scene is good. Finally, some drama! However, I feel like the story is just getting started. But now, it's finished?

  1. Lo único que pude pensar al final fue "¿Y ya?". Creo que todo se deja a la interpretación. Por un minuto piensas que jamás lograron aclarar sus sentimientos y al siguiente el hombre está escribiendo algo en la hoja de papel y todo cambia. Es casi como si estuviera reescribiendo lo que realmente pasó y me deja pensando ¿fue verdad o no? ¿Fue lo que quería que pasara y no se atrevió? ¡¿Ni un beso para toda esa tensión sexual?!

    Todavía no sé si me gustó o me frustró muchísimo esos largos veinte minutos que estuve esperando semana a semana. Sabemos que Strongberry puede hacerlo muy bien, Choco Milk Shake es una prueba de ello, pero, jooooooer ¡¿tres capítulos?! Ni para emocionarme. Aunque estuvo muy lindo, la química se sentía en ellos.

    Por cierto, ya van tres veces que comento -En la película de ZeeNuNew, la serie de Love for Love's Sake y en Mr. Sahara and Toki-kun- y mi comentario por alguna razón se pierde en las oscuridades del Interner y de pura frustración ya no lo vuelvo a intentar. Ahora he aprendido a copiar los mensajes antes de mandarlos hahahaha 😫

  2. This was originally a short film released in 2022, so not sure if we should judge it with the same standard as a regular series. strongberry has made multiple short films before, it seems weird to split this into three parts when it was originally just one short film. but strongberry always excel at delivering the emotion no matter how short it is

  3. I agree that this project suffered from its brevity. There was not enough space to develop the narrative as much as I would have liked and and in any case I would rather have seen the full piece in one go rather than chopped into micro pellets. That having been said, both leads resonated on screen and I can't deny my massive Kim Song Hook bias from his role as Milk in Choco Milk Shake. He was a feline (literally) introvert character there and in this role he's a strappy, confident jock (did he bulk up for this role?) and he's just wonderful in both roles. Absent a nuanced narrative, one thing that Strongberry always does well including here is setting a mood with details. The ASMR attention to sound and textures, for example, the sound of a graphite pencil writing on paper and the sound of a voice (with no intruding background music) reading from a journal create an ambience and a sense of intimacy. I feel that this was a sketch for a film or a series rather than a full production but I still loved it.
