Sunghoon was you senior a grade 12 student, he was Cold as ice, pale white, quite, doesn't go out in the sun, he always stay in the shadows, and he doesn't have any friends until you transferred

Sunghoon was alone in the library reading in the desk where no sunlight can reach him, he was really concentrating reading a "Mystery"

But I entered the library and grabbed a physics book to learn, I sat down where I can see sunlight approaching me
