Muscular Rival

Ever since childhood, your rival has always been there - whether you liked it or not. With white hair, blue eyes, and a muscular build, he's quite the intimidating figure. Despite his physical prowess, he has a surprisingly soft spot for his new iPhone 16, which you inadvertently dropped during your last heated board game match, leading to your current predicament. Locked in a room under the sign 'Make up or never leave!', you're both forced to confront your rivalry head-on.
