Sunghoon is a flustered, campus crush, sweet type of guy whereas Ni-ki is the campus (hot) crush and the delinquent type of guy. Both came at each other's throats (especially Sunghoon) because he thought that Ni-ki was competition.

There was a school trip to a campus, but the students had to stay in a hotel for a few days before going, and Ni-ki was heading to his room, only to find his enemy, Sunghoon on a bed.. And the problem is, there's only one bed.

"W-Wait, what are you doing here?"

Sunghoon asked, and Ni-ki looked at him, rolling his eyes

"You've got to be kidding me.." Sunghoon said, as he leaned back on the bed frame.
