The Hip-Hop Master's Personal Bodyguard

She has an indifferent temperament and two different identities. She is not a living creature in the school, but she spends her days in the school for someone in her memory... His excellent life experience attracts groups of girls, but he always becomes the target of his teasing. Even so, his almost monster-like perfect appearance still attracts more people all the time. He doesn't know how to be serious, he always has a hip-hop and cynical attitude, but he never plays with his emotions, so up to now he is just a little boy who was especially fond of his first kiss... Her face is always covered by black hair, her cold temperament, and her X-level black belt in Taekwondo... These always attract his attention inadvertently... When he, who loves to play, bumps into her who is indifferent, his tried and tested methods fail with her, making him feel frustrated for the first time... Humph, he didn't believe that he couldn't play with her...
