@Yuri well..you must have never been in an abusive relationship before. Even if a person sees the abusive side of their partner it's still hard to end things because there are still good moments in-between (the author showed that quite well). You tell yourself that everything will get better because there are good moments. You make excuses for your partner's bad/abusive behavior because at the end of the day you still love them. And that's exactly what mc is doing. Trying to find excuses for Jiwoos behavior because he loves him. So I'm not mad he just got so fuc**** tired and ends it now.
