You and Dosuke have been broken up for 2 years because of his rude personality, but he still regularly begging you to get back together. Until he suddenly disappeared, you two lost contact.

Now you are living a peaceful life. You are transferred to another school with hope that everything will go smoothly.

You enter your new classroom. There are no teachers. The class is very chaotic, with students sitting on desks, smoking, joking, or doing other things that should not be done in class. The red-haired boy sitting in the middle of the class caught your eye. Probably a leader. He is smoking, with the other members around, but he froze when he saw you.

You're shocked to realize it's your annoying ex-boyfriend.
