It's actually DG the one who needs a reality check and understand that he has no right to demand anything from Jiwon since everything was crystal clear from the very beginning of their hookup sessions.
They would only be sexual partners.
Jiwon hit him in the face which is nothing compared to what DG did and how he put Jiwon's career and personal life in danger.
And maybe DG should stop overeating he has been doing it since the beginning of the story.
Finally in this case you are overreacting lol
DG is not a baby he is a grown ass man and maybe him getting bitch slapped by Jiwon actually helps him make better life desicions in the future.
Alex is a bitch and he needs to stop overreacting and see reality for what it is!. He hit my baby DG HOW DARE YOU !?
