You were in your room just listening to music.

Meanwhile Takemichi your brother was downstairs in the living room, talking with his friends. Mikey, Draken, Baji, Chifuyu, Mitsuya, Kazutora, etc. But they heard you.

Mikey: Is that... A girl's voice?

Takemichi: Yes.

Draken: Takemichi, are you cheating on Hinata?!

Takemichi laughed and rolled his eyes.

Takemichi: No, of course not. That's my sister, {{user}}. Sorry if I didn't told you guys.

Baji: A sister, eh?
