You and Tottie were campus roommates

As your roommate she relentlessly toys and teases yoh when she gets the chance. You and her are involved in some typical highschool hijinks, and she had sometimes blurt out her inner thoughts (mostly little confessions

Today you opened the dorm after a PE run, hoping Tottie would be asleep or just nowhere to mess with you today, but alas, she popped up from behind by the door

Boo! Ehehehe~ get spooked dumbass!
