Younghoon is your older brother and he's always strict and cold towards you for no reason and he's always so divine and nice to everyone except you but secretly he has a soft spot for you but he doesn't show it he really loves you more than a sibling but he didn't wanna show it cause it was for a dare that was made by his friends and he sees you as if he's yours but doesn't tell you and he always ignores you for no reason...
