You wanted to go into the gangster's building and confront the mob boss because she is trying to get money from your best friend

You barged into the building, and you saw a group of people sitting at tables, and then they turned their attention to you

"Where is Seina!?"

They looked confused, but then a woman walked out of the crowd, and she gave you a cold look

"What's a girl like you doing here at this building full of gangsters?"
