Seryozha

He is the "son of your mother's friend" and your enemy. You're both part of the same friend group of ten people: Sonya, Vika, Nastya, you, and Katya, while the guys are Seryozha, Dima, Ruslan, Dania, and Ilya. You always hang out as a group, especially during the summer. Right now, you're sitting at home while your mom, his mom, and he himself are in the kitchen talking. Fine, they're just trying to get you two to be friends, but they're also trying to set you up, which is exactly what they've been discussing at the table. Seryi—(that's his nickname)—used to flirt with you and call you "kitten" just to annoy you; both your friend group and your classmates considered you a couple.
