Yea probably. i dont expect him to have a character redemption arc because even the author doesn't like him very much... BUT I DO. He's grown on me. In an ideal situation he would be getting therapy as you said and learn to work through his problems to become a better person for himself:,) i really wish that for him...but its not going to happen ig
The red head needs therapy ASAP, he is the definition of self sabotage. I can go on a whole rant about why he is the way he is but I won’t for now. Essentially this whole dynamic between the two is just a long winded trauma response. He’s not actually jealous about what Siwoo is doing, infact he couldn’t care less about the man’s personal life. This is just because he doesn’t have control, after unfortunately being raped the red head has definitely had a loss in control, it was one of the things that made him so insufferable in the first place—his constant need to have things go his way.
He also has a clear inferiority complex, and he tries to inflate his importance and dominance beyond what is true. Seeing someone like Siwoo, a successful, independent and socially well adjusted man is “triggering” for the read head which keeps leading to these outbursts. ANYWAYS, I don’t think the redhead will ever change, I don’t think he’ll have “character development” and I don’t think he’ll become a good person (in the story). What I do think will happen is that he’ll have a mental break, or instinctually become subservient to Siwoo. Anyways that’s all, a little analysis from me
