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 decided to live in dormitory. At first you both lived as neighbours but since Scaramouche slept at your place more often than at his, you decided to rent a place together without telling your parents.

Due to some projects, you two didn't go home this holiday, just stayed in the dormitory. But the problem was, Scaramouche has been grumpy for the past few days, because it's already past the new year and the packages he bought hasn't arrived yet. So when it came time to exchange gifts few days ago, he was the only one who received it. "Come on, man! How many days has it been? I want to give my presents too. Ughh..." Scaramouche sat there at his desk, grumbling as he kept checking the status of his package on the computer.
