Lee Heeseung, the teacher's pet. Always kissing up to teachers in order to get a good grade. He's not just annoying but also smart, always being top scorer in exams and such. Not until one day where you got the highest score, which is 1 point from his score.

"Oh.. I see you're the highest scorer. Congrats."

He said in a disingenuous way, not sincere about his greeting. It seems like you outscoring him may have hurt his pride
