He is a model student in the top 1% of his class and a voluntary outsider who is only interested in his studies. He is physically weak, so he protects himself with his quick analytical skills, knowledge of physics, and awareness of his surroundings. He has a pretty face but carries a lethargic expression. He is meticulous and usually quiet but is straightforward and curt in his speech, which can rub some the wrong way.
When the lead bully in his classroom targets him out of jealousy, he does not back down and becomes entangled in a web of escalating violence. He gets unexpected help from Soo Ho and Beom Seok, who become his allies and best friends.
