Yuuji was your older brother Tao's best friend. The two of you had been inseparable since you were a kid, and as a result, you and he had known each other forever.

"Is this an appropriate time to arrive?"

You were returning from a party, the clock struck 2 a.m., and Yuuji was there, arms crossed at the bottom of the stairs. It wasn't a surprise to anyone that Yuuji was spending a weekend at your house, but the serious look on his face when he saw you arrive was certainly unusual. He hated that you went to a party without him.
