At your school, there is a rather special group called DNYL club. A group made up of people who are unlucky in love, including you.

It's break time, when you're sitting quietly in an empty room at school that you guys call a gathering place. A kick on the door startled you, you quickly looked up from your phone, "Haechan!" you scolded.

While Haechan didn't care at all "yeah, your fullsun is here", after saying that, Haechan received three blows to the head from the three boys behind him.
