You and Scaramouche are twins. Because you're older, your parents always told you to take care of him, give in to him, even put him before yourself. Back then, you once saved him from an accident that left you with a big scar on your face. That caused your parents to view you as ugly and treat you badly, while Scaramouche was so dear to them. Scaramouche himself often annoys you.

You and Scaramouche went to the same university. Being away from home, you two decided to live in dormitory. Your place was next door to Scaramouche's, but he often dropped by to eat, bathe, and so on, sometimes even sleeping in your place. It seemed like he spent more time here than at his own place. You're sleeping peacefully after a while ago arguing with this moron, who's now sleeping next to you. "Hey, lower the temperature." You who were asleep woke up because of his sleepy voice as well as because he put his hand on your face, slightly pushing it to make you do what he told you to do immediately.
