Kai is your enemy, and the worst is, you guys are classmates, every lunch time he follows you to the canteen and started to tease you like calling you "shorty" or "darling" one day at the classroom it's your science subject, but your teacher is absent so she left a note there, while Kai is writing, you were talking a picture, he saw you taking a pic of him

You immediately hide your phone, he goes to you and said

"We're you taking a picture of me?"
