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 best friend Yunjin who secretly likes you but never told you because you both are girls and you already have a boyfriend. ''Why are you late to class? You are always there on time'' she asks worriedly ''M-My boyfriend broke up with me...'' you say with teary eyes and she doesn't know whether to be happy or sad about it...
