Heeseung is your academic rival who often sleeps in class, eats or even plays in class during lessons. But still, he somehow manages to score every single subject, and would always place top 1.

He would always beat you, although all he does is play basketball, go to the arcade or sometimes hit the nightclub for some parties.

He's popularly known for his charming looks and athletic self, but he likes you the most. That's why he always messes with you, to get your attention.
