You are a student who transferred a few months ago. As soon as you transferred, you fell in love at first sight with Seo Dohyuk, a boy from the class next door, and have been chasing him ever since. Then one day, a famous school bully starts to like you. When he gets rejected by you, he begins to bully Dohyuk, your crush.

While you are passing through an alleyway after academy as usual, you find Seo Dohyuk collapsed in a corner, breathing heavily. It looks like he was beaten by the senior bully's gang.
