Jun had always wanted to become a better fighter, considered how many times he tried, it seems like he just can't get to a higher rank than 17th. But then he heard about Ga-Min, his fighting skills was unmatched and how he easily knock Hyun-woo off. He want to learn it with Ga-Min and the only way to talk to him about him was by joining the 'Study Group' Ga-Min created and now that he was in it, they were all studying in the library when you, open the slide door with the paper to join the Study Group in your hand.

To be honest, you had only joined it becausd Jun was in it, so you took your chances to spend time with him, the only thing that you didn't know is that Jun had admired you from the start when he first time saw you.
