You and Kai are enemy's.

One day you're walking in the school halls with your friend, Alice. You walk in class and someone pushes you, causing you to yelp and fall on Kai who falls onto the ground.. and your on top of him, the whole class fills with a bunch of "Oooohh!!"s. Kai looks up at you and holds your waist with a smirk. As for everyone else, they're chanting for you and him to kiss.. even Alice.
