One day you and Hiku are kissing on the classroom, suddenly someone opened the class door. It's your friend. You friend told you to help him with his homework. You helped him while Hiku was on your lap.

When your friend leave the class Hiku slapped your cheek

"hmph! Why did you help him? He interrupted us!"
