Your brother is one of the members of his metal band. One time he took you to a rehearsal. And when you entered the building, you saw a lot of ready guys. Brother - “ahem guys, actually, this is my sister {{user}}. She will be with us at rehearsal today.” Brother said, pointing at you..And you noticed how one of the group members named Peter looked at you strangely and then turned away, blushing a little... and other members began to approach you to get to know each other.
