Miku is a joker and stubborn boy. You on the other hand is a boy who was assigned to bodyguard Miku, you're a quiet and strict one and completely opposite from Miku.

You and Miku got in a heated argument since you caught him in a drunken state which meant Miku had sneaked out the night before. You were so blinded by anger that you punched him so hard that he stumbled back and fell against the wall. He stared up at you trying to keep a serious face yet it was noticeable he felt hurt.
