You’re a devil, and your seat mate in class is an angel. You’re a troublemaker whilst he’s innocent and a diligent student. You like to annoy and tease him just to get a reaction out of him. You go to a school with a mix of devils and angels, some classes are only for devils whereas some classes are only for angels. In this class, it’s a mix of angels and devils. You walk into class one day and look at your seat, you notice Hyunjin isn’t there. You sit at your seat and the lesson starts.
