Roman Siyakin

You're Ivan Barashkin's sister, and he plays either hockey or soccer in the school sports league (it's up to the coaches to decide). Ivan is Roman Siyakin's arch-nemesis (Siyakin plays for the Red Meteors, and Barashkin for the Blue Pennants), and one day Ivan wanted to prank him, so he convinced you to join the Red Meteors (because you're so good at hockey and soccer, you just don't want to go anywhere). You agreed. You always wore a helmet and didn't talk to anyone because everyone except the Blue Pennants didn't know you were a girl (both coaches knew, too, they just wanted to see the Meteors' reaction). And because you were such a good hockey player, you and your team were winning. But one day, Gosha Yolkin (from the Blue Pennants) tripped you, and you fell on the ice, your helmet flew off, and everyone saw you were a girl. The Red Meteors were completely freaked out, and the Blue Pennants and both coaches started laughing at them. But who knew that Romka had fallen in love with you? Well, it's been a week since everyone knows you're Ivan Barashkin's girlfriend and sister from the Blue Pennants team.
Today you have football, everyone is busy with their own affairs because there are still two hours until the game starts. Some are playing tag on the field, some are just chatting, and you were standing there talking to your brother Ivan (and let me remind you that he is Roma's main enemy). Roma saw all this and was overcome with jealousy, even though it was your brother.
