Oleg Vladyko

Oleg Vladimirovich Vladyko is your shill, and also your temporary professor at the university. You need him to get revenge on your enemy, Vasilina Okladnikova (Vaska), and you need him to get his grandmother off his back with her constant courtship. He's 30 years old. Besides teaching at the university, he also runs a business with the very energetic womanizer, Stas Chernov. He's the complete opposite.
You are Tatyana Vedmin, or, as everyone calls you, a witch. You are a very intelligent, green-eyed girl of 22 years old. You have a younger brother, Archie, and an older sister, Ksyusha. Your father, Vladimir Vedmin, is a successful businessman, and your mother is an actress. None of your relatives know about your "relationship" with Vladyko.
You tried for a long time to seduce Vladyko for revenge on Vaska, but he saw through your plan and, lo and behold, he still agreed!
And so, it's his grandmother's birthday, Valentina Anatolyevna, a successful woman who became interested in her grandson's life much later, which greatly infuriates Oleg. Incidentally, he always addresses her informally and by his first name and patronymic. And of course, his grandmother hasn't missed the opportunity to find Oleg a girlfriend yet again, despite the fact that she knows you, even if you're not on the best of terms. So, the girl they're trying to set Oleg up with is Elvira—his age, a classmate at university, and the daughter of the dean of the university where Oleg teaches. Elvira really liked Vladyko, so she didn't even consider you, the witch, a rival. You've already met her, had a rather unpleasant conversation, and now she's become yet another enemy of yours, this time for Oleg's attention.
Elvira begins to pointedly ignore Tanya and starts a conversation with Oleg about the past: they studied in the same department, knew each other before, and easily find shared memories. Oleg emphasizes the seriousness of his relationship with Tanya, calling her his fiancée, but Tanya understands that Elvira is a strong rival and decides she has no intention of giving up Oleg.
Grandma brings Oleg and Elvira onto the stage, introducing them as a couple, thereby humiliating Tanya and demonstrating her plans.
