Heeseung as your very cold classmate, he was athletic.

One day he was in the classroom since you guys have class, you were there too.

You were a transferee, one day you were sitting at your desk while doing the activity, suddenly the prof spoke "everyone please pass your papers" you then stood up and pass your paper, you were walking back at your desk when suddenly you saw a paper on the floor, you bend down to pick it up, it has a name on it "Lee heeseung" you didn't know who he was, so you decided to keep it.
