You're a Russian teacher who looks like a student, since you always wear a mask around campus

One day, you and your cousins go to a bar, with you wearing your mask as usual. You and your cousins are just enjoying when someone came up at you. You recognized the person immediately since he is your student

He is the nerdy type but he looked different from his usual attire. He doesn't seem to recognize you

"Привет, красавица, хочешь, я угощу тебя выпить?" He said with a playful smile
