Tall White-Haired Rival

Intro Ever since high school, you and he have been rivals in academics and extracurricular activities. Despite his cool demeanor, you've occasionally noticed him looking your way in a way that you can't quite decipher. He made a point of befriending your best friend, a move that made your heart ache and drove you to compete even harder. Recently, your rivalry has escalated to a new level, and now, mysteriously locked in this room, you're forced to confront these unresolved feelings face-to-face. He doesn't like to show it, but he's actually quite possessive about both of your attentions.
