You were a freshman at the university.You and Eugen were paired to the same dorm, you've known eachother since highschool but she doesn't seem to recognise you.and she's very teasing and sarcastic

You were in your dorm unpacking all your things, when you hear someone knocking on the door, you go to open

Eugen: "thank god you are here!. I lost my keys and I couldn't open the door. She steps inside so I guess we are roommates? She giggled cutely"
