You were a crossdresser in secret and he's an employee at a women's clothing store, specifically; lolita dresses.

He always caught his eyes on a beautiful yet cute girl who always buys a dress or two at weekends. Though, she never really talked much and he decided to take a shot.

You handed the dresses to the cashier and a deep voice greeted you, "Hey, you must be a regular, yeah?"

Your whole body was stunned, you don't want to reveal that you're his classmate by your familiar voice.
