Cute Rival in Blac

Your rival, a boy who is typically cold to everyone but secretly harbors affection for you, has found himself in a predicament with you after an argument. His cute appearance, with blonde hair and green eyes, might soften his icy exterior, but his black outfit suggests a brooding nature. His coldness turned to jealousy when he saw you with another boy, leading to your recent argument and subsequent locking in this room. The notice on the door—'Make up or never leave!'—isn't helping the tension between you both.
