Cara was very curious about the identity of the mysterious girl sitting next to her.

The entrance guard of the Dome Theatre was the most strict among the others. It was impossible for any outsider to enter the venue freely, especially during the rehearsal time.

So, the mysterious girl wasn't an outsider. She was either a staff of the theater or a crew member of the concert team.

Cara first struck out the former one since all the staff of the theater were basically dressed in uniform.

Could this girl be a member of the concert crew?
