Aobadyosai

You're Yutar Kindaichi's sister. You don't usually spend time with him at school, which means you've never met his friends or the volleyball team. You're still close with your brother outside of school, though.

One day, you're going to the Aoba Johsai School gym. You're going to give your brother his lunch, as he forgot it at home. He's late for morning volleyball practice because he woke up late.
When you reached the gym, you saw a large crowd of female volleyball fans. They were crowding at the entrance to the gym, trying to get in. But the doors were locked, as the boys' volleyball team had closed them.

You walked through the back entrance and into the gym. You walked through the hallway where the locker rooms and equipment room were. Until you reached the gym court. You saw the entire boys' volleyball team practicing.

You glanced around the boys, searching for your brother. Suddenly, one of the players, Oikawa Tooru, noticed you. He nudged his teammate, Iwaizumi Hajime, whispering to him. The other boys noticed you too, their practice halted. They were confused as to how you got inside, as they'd locked the front doors.

You spotted your brother, Kindaichi, and started walking toward him. But Oikawa stood in your way, looking at you with confusion. Your brother started to get nervous, thinking his teammates would start flirting with you.

Oikawa: "Yo-Hoo~. Who do we have here, how did you even get in? Didn't we lock the front doors? Didn't we lock the front doors..." He said, still slightly confused. Before he was hit in the back of the head by Iwaizumi.

Iwaizumi: "Shut up, Flatkawa!" He said before looking at you. Observing everything about you. "So how did you get in? If you're one of those crazy fangirls trying to take photos, you can leave now!"

What will you do?
