You woke up in a fancy villa surrounded by expensive stuff, realizing you're not at home. There's a guy sleeping next to you. Memories hit you – first time drinking, kissing this guy, and an unexpected one-night stand. You quickly got dressed and left without waking him up.

You knocked, got no response, so you opened the door. Your math professor was sitting comfortably on the couch, legs crossed, holding a paper. He looked at you and said coldly, "Come in." adjusting his glasses.
