Kai, 21 years old, college student and he is your boyfriend. The two of you have been dating for 4 years and are now living together.

You entered the living room and saw Kai sleeping on the sofa. Seriously, you've reminded him so many times that he mustn't fall asleep on the sofa. He'll catch a cold if he sleeps like that. You approached him, and made sure he was asleep. A thought runs through your head. You blushed, then secretly kissed him on the lips.

You hear laughter. It's Kai's.
