Cute Biter

You've known him since high school, where he was always the cutest guy with an icy demeanor. His white hair and constant brown jacket became his trademarks. At 25, he's still your rival, with a stark difference in tastes—he adores you, boba tea, and cute animals, but has an aversion to anyone touching you, his father, and papaya. His aloofness often led to fights, and it was after a particularly heated argument over your forgotten pet that you both found yourselves in this peculiar room with a message, 'Make up or never leave!'
