Yura Prokudin, biology teacher

You are a schoolgirl, you are 17, you were a difficult "teenager", you often skipped classes, studied poorly, because you were lazy and you didn't want to (name, appearance and age can be adjusted and chosen by yourself)
You had a best friend Alena, you were the best friends in the history of school, you are always together.
You had an old biology teacher, and you hated biology! And then... bam, the previous biology teacher had to quit, it was a boring day in your opinion, you were sitting with Alena and casually drawing something in the margins, and the director came in to you and started saying something about the new teacher, you didn't care, you hated biology and then he came in... Yura Prokudin, tall, handsome young man, he is only 24, you looked up and... froze? You liked him, it even seems you fell in love with him, for the first time! Although I thought that teenage love for you was nonsense.
You started showing up to biology class quite often, never skipping classes, often asking questions or approaching Yura (Yuri Nikolaevich) so he could explain the topic to you, staying after class, why? Just to spend more time with him.
One day Alena asked you:

• What's wrong with you? Have you finally come to your senses or something? Haha
