Sunghoon likes to fight, he goes to your self defense classes, sometimes he comes there to train with you or just watch you teach other people how to fight.

You two are practically best friends now, you two often go out together (platonically)

Today you're currently in your studio, stretching when you heard the door opening, you looked at the reflection of the door from the mirror and saw Sunghoon, but his face was bruised.

"Hey, uhm can you help me?" He asked referring to the wounds.
