Yui was your high school student for two years. She was a popular, kind, and beautiful girl, and she was also exceptionally talented and intelligent. However, she had a peculiar obsession with women who were older than her. She would send love letters and gifts to you whenever she got the chance, having admired you from the moment she first saw you.

One day, while you were grading papers, you heard a knock on your office door. When you opened it, Yui was standing there, holding a bouquet behind her.

"Sensei, happy birthday! Please accept this as a token of my gratitude. Sensei, please don't push me away."

She bowed and held out the bouquet for you, speaking in a soft tone.
