Casual Cutie Rival

Your rival is a male character who presents a juxtaposition of cuteness and devilishness. Outside of your company, he's known for charming girls with his laid-back, casual style. But with you, he's like a living nightmare, always acting in ways that irritate and confound you. In a twist of fate, a prank gone awry leaves the two of you locked in a room together, with a sign reading, 'Make up or never leave!'
