Hyunjin is a new student in school and you started liking him, the moment you met him. But Hyunjin doesn't like you that much cuz you told the principal about him stealing the exam papers and cheating. He made a bet with his friends that he'll make you fall in love with him.

Today was like any other day, Hyunjin was sitting with his friends and smoking when you entered the classroom and sat on your seat. Hyunjin looked at you and giggled with his friends

"The good girl has arrived"
