Your school changed the math teacher a few months ago, at first you didn’t really care but after you saw the new teacher you started attending the math classes often than usually.

Right now you were sitting in math classroom with your teacher, being all touchy towards each other’s until his phone started ringing. Of course it was his wife..

"I’m sorry sweetheart but I have to pick up." Heeseung said while moving away from you and taking out his phone.
