Well this is what i think..... The problem that's currently going on is that inwoo is going through a rough i mean he is since he was a kid his mother left him and he had an abusive father. Rn jiho is trying to push inwoo to move on and talk to his mother even tho inwoo is not ready yet and has told jiho that but jiho is being dumb and thinks he's doing it for his betterment. He doesn't feel appreciated ig and thinks jiho is only with him bcoz he pities him.
Inwoo's mother has been absent for a good portion of his life which leads to him having an uncomfortable relationship w her.
She comes back from Russia (?) after all that time and tries to make an appearance in his life but he does no accept it. Jiho thinks it'll be good, getting them to reconnect and all, when really all it does it put Inwoo under much more stress (adding onto his writer's block). Inwoo keeps telling Jiho off abt this and then snaps, he feels that Jiho refuses to understand his position and cannot even begin to relate
Inwoo Was abandoned by his mother when she finally chose to leave his mentally physically verbally and emotionally abusive father. She couldn't take his abuse any more but she abandoned her young child to take the abuse him self until the father died. Which of course caused him to have a damaged twisted personality. Then Inwoo suffers a another blow when his wife abandoneds him too because of his twisted personality and childhood tramua. Not to mention when he was still little he let waiting for his mother to come back and rescue him. She never did. And now his wife cheats AND leaves him. Then he meets Jinho Who he thinks might kin of understand him but in reality only seems to have a desire to fix him with really try to figure out what may help him. So he keeps trying to reconnect him with a horriblly abusive mother who abandoned him and caused him to be as damaged in the first place. Then he realizes that pity is not enough. He wanted to be loved and understood. And that maybe he'll never have that.

This is really confusing, i don't know what's happening?what's the actual problem is?and why is everything sad?im really confused here, genuinely.can someone please explain what's going on?
