Why everyone hates Hwan?

Men, i cried while reading this and it really hurt me seeing all of the comments hating on Hwan, it he is the most pitiful one in the manhwa. I mean, he was a kid passing through a hard time and he really never mourned, Chiwoo was like a rope for him to just get up, he was clearly in depression when his dad died, his mom just neglected him all the manhwa, she never, not even one time, put herself onto his OWN SON side, she never tried to talk with him (not even when he was a child) or making him go out little by little out of his depression, cause lets be clear here even if I'm overthinking, he was clearly in depression this whole manhwa, since he was a child and no one tried to be with him. He gave himself to Chiwoo, he console him, he cheered for him, love him but Chiwoo didnt tried to have a talk with him, he saw Hwan as this perfect winner of life perspective of Hwan when in reality he was in pain all the time. The first time they have sex both of them were drunk and he was overjoyed by the fact that Chiwoo like him back just to wake up to Chiwoo moving out, imagine that, you think you start a relationship with ur crush just to wake and seeing him leave you as like he just used you without any explication, Chiwoo really looked like he was rejecting him. Chiwoo never tried to get in contact with Hwan, he just accepted whatever he gave to him without giving him something in exchange. All the monsters that SA Chiwoo were made BEFORE Hwan knew that Chiwoo was the other contractor, when he realise he stoped doing them just to find out again Chiwoo leaving him and in their begining life of dating started caring about other gay without telling you (╯°Д °)╯╧╧. Thats just awfult, i really feel sorry for Hwan, Chiwoo wish was for Hwan to be with him but he left him always, Hwan wish was for staying together always with Chiwoo making him happy, now who is the really selfminded? Hwan deserved a caring mother more than nothing, if his mother really cared about him a lot of these manhwa never really had happened.

Sorry for the long comment and for my bad english, not my first language. Not sorry for Chiwoo tho, he can suck others dicks if he wants, just makes Hwan forget about him and find someone who really care about him like he do. (If someone tells me that Chiwoo cared about Hwan ☠☠, like he really started to worry when he saw that Hwan was CRAZY, before nothing, even when Hwan was visually impacted when he killed Jin or it was before? Whatever, but the first reaction of Chiwoo was break up with Hwan, like wtf?? Not a talk? Not asking? Not making up points? Not trying to understand? Like i understand that Chiwoo was sad about Jin but like, he didnt tried to make sense of the actions of Hwan, and even when the conflict started with Jin, he never tried to explain it to Hwan, he just protected Jin as if Jin was more important to him that Hwan, that obviously will trigger something, imagine that ur boyfriend LIVES with other person without telling you knowing that that person likes him and even more, put him before you (●'◡'●)ﾉ i will also go crazy)
