Kangin is known for being the tough guy. Even before he enters the campus, he's been the 'bully' guy. Leeteuk knew that ever since. Kangin is like a brother to him. He's always been there for him. The reason he always ask himself why Kangin became the guy he is now. Though, he also knew that Kangin has an attitude problem. 

At the campus...

Eunhyuk is walking in the hallway with a pile of documents he carries. The same time Kangin pass by. "Eunhyuk ah" Kangin speaks. Eunhyuk halt and turn around to ask Kangin "What?" he says.
