Fight for You is a Taiwanese BL series about a police detective on an undercover mission. The main character is assigned to investigate a shady company with suspected ties to criminal activity.

Plot

Bai Zhou Qi, also known as Xiao Bai, is a police detective from a long line of law enforcement officers. His grandfather is a cop. His older brother, Da Bai, followed the same path. Xiao Bai joins the force as well, continuing the family tradition. His grandfather is a strict man with a strong sense of justice, seeing the world in black and white. Xiao Bai grows up with these beliefs, carrying a heavy sense of pressure to live up to them. That pressure feels even stronger because he has always lived in his older brother's shadow.
Xiao Bai works for the Police Intelligence Bureau. His supervisor is Bu Xing, better known as No Sir, a Hong Kong cop stationed in Taiwan. No Sir assigns Xiao Bai an undercover mission. He must investigate Hei Yu Bo, a new employee at the Anything's Possible Agency. On the surface, the business helps customers run everyday errands, making their lives more convenient. As the motto says, anything is possible. However, the police suspect the agency is a front. No Sir believes the company has ties to criminal activity, and he wants Xiao Bai to confirm it by getting close to one of the staff.
Hei Yu Bo, also known as Da Hei, is single and looking for a new place to live. He used to stay with his grandma, but it's time for him to move out. She believes her grandson is moving in with a girlfriend, which is a complete lie. In reality, Da Hei knows his new job at the Anything's Possible Agency comes with risks, so he doesn't want to drag his grandma into it or make her worry. While touring apartments, Da Hei meets Xiao Bai. He doesn't realize Xiao Bai is secretly a cop, posing as a potential roommate to investigate him.
Xiao Bai and Da Hei move in together. Xiao Bai pretends to be an innocent university student while secretly spying on his roommate. Da Hei doesn't question his background, even though he notices how curious Xiao Bai is about his job. Soon, Xiao Bai learns that Da Hei is desperate for money. His sister is in the hospital and waiting for surgery, but he's struggling to cover her medical bills. It's a secret he keeps from his grandma, who believes her granddaughter is studying abroad. She has no idea about Jia Li's health condition.
Brother Dou owns the Anything's Possible Agency. He's aware of Da Hei's financial situation and offers to lend him the money. Da Hei is proud and refuses to take it for free, promising instead to pay his friend back by working at the business. For now, Brother Dou only gives him manual labour jobs. They are tough, but nothing illegal. Brother Dou is extremely cautious with his company. Xiao Bai soon realizes this assignment will not be over quickly. He'll need to build a real friendship to earn Da Hei's trust and wait patiently for a breakthrough in the case.

Fight for You Review
Review
Drama Review Score: 8.1

Fight for You grew on me over time, but it began slowly. Episode 1 is a bit… meh. The leads move in, they chit-chat, and I'm waiting for something to happen. I sat through it, but I wasn't glued to the screen. Episode 2? It's improving. The roommate dynamic is funny. I can start to feel the couple's chemistry. By Episode 3, the story has warmed up. Around this time, Xiao Bai and Da Hei become a lot closer. As they flirt more, every episode gets better. Now, I care whether these two idiots figure out they like each other.
Xiao Bai and Da Hei are ridiculously cute together! Making them roommates from the start was a genius move, because we skip the slow buildup and go straight to their cozy domestic moments. I love watching them flirt, get all flustered, share a drunken kiss, and then pretend it didn't mean anything. Spoiler alert: it meant something! The romantic fluff is what I enjoy most about Fight for You. It finds creative ways to put the couple in hilariously intimate scenarios. In Episode 5, the seduction scene is BL gold. Another classic moment is Da Hei's strip tease in Episode 6, as this sweet himbo character shows off his sexy side.
We get plenty of cute moments, but each character also has storylines to give them more depth. Da Hei's sister is sick, and his grandma is clueless about what's going on. Watching Da Hei juggle his family drama makes him feel like an actual person. Meanwhile, Xiao Bai lives a double life as an undercover cop. His job complicates everything. By the time you are deep into the series, you know who these men are, where they come from, and who they care about. Both leads have strong identities and personalities, which is so important for making a memorable BL drama.
Xiao Bai's actor (Nelson Ji) is a certified cutie with an angelic smile. He shows off his natural charm in the fluffy romantic scenes. His co-star (Andy Ko) won me over as the series went on. There's a sincerity in his eyes that sneaks up on you. When his expression softens… When he looks at Xiao Bai with a pitiful glance and dopey little smile… It's incredibly effective. Their performances aren't flawless. Both leads have some shaky moments here and there. Still, I appreciate how comfortable they are with physical intimacy. These two are constantly making out, and I'm loving it!
Fight for You seems more interested in romantic fluff than in developing its story. Xiao Bai is investigating Da Hei's ties to a crime syndicate. Whoa! That sounds scary. Maybe Da Hei gets dragged deeper into illegal activities… Nope! Whenever Da Hei is in any danger, these moments feel poorly executed. A threatening scene will pop up out of nowhere, with zero buildup and little explanation. And then, it's over without lasting consequences. The crime drama causes mild inconvenience, but it never escalates. Annoyingly, the tension stops before it can even get intense.
The police investigation never goes anywhere interesting. Don't get your hopes up for this plot, because it stays extremely basic. The last few episodes take a hard pivot into full-on Asian melodrama. Da Hei drops to his knees to beg for forgiveness! Xiao Bai cries into his bowl of rice! Oh my god, everything is so over the top that it entertains me. Thankfully, the story still has a happy ending. The finale is super romantic, flooding us with cutesy moments. Overall, I liked Fight for You! Despite the lacklustre plot, this BL drama has an adorable couple with a really sweet relationship.
