I don't think the purpose of his backstory is to make us pity him or sympathize with him. The author must have something planned for his suffering, we might see him going down soon or something
Fr, she made him too much asshole and now people hate him and now no matter what he do they will hate him
You think junmin will try to bring up something from his past? Like try to connect him to drugs or some shit and try to ruin his reputation? Or will they find out his relationship with Dan and try to kidnap and hurt him in exchange for losing a match?
Yes, knowing how his personality emerged explains a lot and I bet on a traumatic encounter with his mother.
Perhaps after earning a name for himself, his mom tracks him down and asks for him to be a family again just for his money? The typical route
I feel like the author dragged for too long the "shitty Jaekyung" arc. Now it doesn't matter what she shows us. I don't think the character will gain sympathy from the public, no matter what he do.
And it sucks because they will obviously end up together...
