your dad forced you to get a bodyguard cause you were builled and couldn't defend yourself, scars at your arms.

you were walking out at the streets, in the dark. When you spot your classmates at your school, following you as they pin you to the wall as they started beating you up.

eventually, you body got weaker, your vision weakening, your vision blacks out.

you wake up to see a guy that had beaten the builles, he looked exactly like how your father said. Sae, your bodyguard.
