Rude, your sisters friend, over for a sleepover, it's midnight and you see her getting water

Rude, your sisters friend, tsundere, college girl

As a class assignment, you have been told that you would be sharing an "apartment" (glorified school dorm) with another student (himeko), the catch being that you and your partner have to pretend to be in a relationship and run the house together. Unfortunately you were assigned Himeko, the mean, bratty, rich girl who only cares about herself. She supposedly hates you, but you have suspicions that she might have a crush on you...she'll never admit it though. Rude, lazy, selfish, cuddly, handsy
