I don't speak for everyone but I can give some of my reasons for disliking him.
Taku only first took interest in Haesoo because of his relationship with Joowon and thought it was interesting. Even in his photoshoot with Haesoo he makes Haesoo think of Joowon in order to get the emotion on camera.
Taku manipulated Haesoo from the very beginning of their relationship with the use of his sex tape, trying to make Haesoo write about it and in turn feel guilty to try and make Haesoo choose him.
Taku again emotionally manipulated Haesoo into a relationship he clearly was not ready for after Haesoo explicitly told him he was not ready for a relationship.
Taku has been outwardly antagonistic towards Joowon even when Joowon knew nothing about Taku's relationship with Haesoo. Even in a professional setting during Taku's photoshoot with Joowon Taku is trying to provoke Joowon.
I'm sure there are even more than this but this is just a list off the top of my head.
Its not that I just don't like Taku, he frustrates me because his intentions and motives throughout the story have not been pure or innocent. His role in this story is to be a shit stirrer. He has been malicious and manipulative with Haesoo and Joowon in order to achieve his ends which makes him an interesting character but not a good person. Now that he has developed some genuine feelings for Haesoo he is so desperate to hold onto Haesoo that he doesnt really care about Haesoo's feelings. He seems to think that if he can just hold onto Haesoo long enough all the past issues and feelings will just disappear. it don't work like that.
and now that Taku does have feelings for Haesoo he tries to act like an innocent angel when he is actually the one responsible for the issues that he and Haesoo are facing.
From the very beginning to me it was obvious that Taku was not telling the truth about his motives, and then when we did find out his true motive he acted like it was all ok since he actually cared about Haesoo now. Im just not down for that. While other characters certainly have their flaws, Taku was the only one who was malicious when unprovoked. He did things with the sole purpose of hurting people and I don't like people like that.
oh and he has had no redemption for his bad behavior. in fact, he doubled down on it and justified himself by saying "this is how I like you in my own selfish way" like great, so you get to be an asshole and im just supposed to forgive/overlook everything you've done cuz you care now? uh no, im not here for forgiving people who arnt sorry.
Yes, i feel you(๑•ㅂ•)و✧
