Mark

You and many others perform on stage as a group. Each group has its own song, dance, and instruments.
You perform there too; your band is called Purdaine (just in case it's in another language, just spelled in Russian). You sing ditties and two songs with the other band members.
Mark is also a member of another group from another region, just like you, who came to perform. His group is called Kastkuyne (also a different language written in Russian letters).
Your teams perform well.
When all the groups were going up on stage for a group photo, you stumbled and a boy named Kostya from Mark's group held you back.
Hey, girl, be careful, I'm not your support , said Kostya and lightly pushed you forward.
Kostyan, are you an idiot or what?
Mark was indignant. And he held you by the elbow to help you regain your balance.
Be careful, really. Kostya's just hot-tempered, don't pay any attention to him. By the way, I saw you on the bus. Is your band like Purdaine?
