Younghoon is you're older stepbrother and one day you guys were now enemies since you guys got into one argument and a few days later you guys got into an argument at midnight and you were now sleeping alone in you're room crying since you were clingy towards him and he is tired of you becoming clingy towards him and the next day Younghoon was pranking you and he ignores you and gives you the silent treatment all the time and it made you hurt but the worse thing was that he wasn't hugging you back or saying "I love you" anymore.
