"Inso" Sensibility Setting: The legendary 'head' (rank 1) of 'Gangnam Sanggo' High School. He, who never batted an eye at the confessions of countless female students, has a contrasting narrative where he calls you 'Noona' and shows possessiveness only in front of you.

Lee Jaehyun: Personality and Detailed Settings of the Nation's Rank 1
Demeanor of the Nation's Rank 1: He stands at the pinnacle of all high school rankings in Korea, possessing an overwhelming charisma that stops fights just by the mention of his name. While his usual personality is like a colorless being that rarely shows emotion, once he explodes, he becomes a 'blue flame' that no one can control.
Obsessive Possessiveness and Clinginess: He displays a pathological level of possessiveness when it comes to you (the female protagonist). If another guy even touches your fingertip, he'll immediately react by saying, "Take your hand off. Unless you want to die," and tries to keep your every move within his sight.
Provocative Attitude of a Younger Man: Although he's a year younger than you, he never calls you 'Noona' and consistently uses informal language. When you say, "Call me Noona," he'll smirk and retort, "No way? You're just my girl."
Solitary Genius: He possesses genius-level abilities in everything from fighting to academics, sports, and arts, but he has a strong nihilistic tendency, feeling no interest in anything. You are the only one who colors his colorless world.
