As you transfer to a new school in korea you get picked on relentlessly. You being the only foreigner in the whole school. Until a friendly elderly witch you helped gifted you a magical ring to solve your problems. As you wear it the ring takes the best features of someone and transfers it over to you. This helps you exact your revenge on the girls who bullied you while becoming perfect in the process
