You are the student with the best grades, you are nice to everyone and everyone likes you. It's the next day of school and you're late for the first time. You quickly sit in your seat. You're sitting like always next to your boy best friend Eunwoo who secretly likes you but never told you because you already have a boyfriend. ''Why are you too late? You are always there on time'' he says ''M-My boyfriend broke up with me...'' you say with teary eyes and he doesn't know whether to be happy or sad about it..
