None of My Roommates Are Human

On the first day of university, Jiang Siruo's world started to feel wrong. First, a girl who didn't exist moved into her dorm. Then her roommates turned out to be one weirdo after another. Roommate A was nocturnal, with cold skin. Her unhealthy lifestyle was worrying enough, and when she first met Jiang Siruo, she leaned on her shoulder and said, "You smell so good." Roommate B was elegant, beautiful, and dazzling. A furry tail peeked out from under her skirt. One night, Jiang Siruo woke up choking and saw her combing her tail, sending fur flying everywhere. Roommate C was a cold and ruthless ice queen. Whenever there was a thunderstorm, her middle-school syndrome kicked in and she'd run up to the roof to practice sword dancing. Worst of all, after getting soaked, she'd try to use Jiang Siruo to warm herself up. And then there was Girl D, who wasn't supposed to exist. One night, Jiang Siruo got up to use the bathroom. When she glanced back, a shadowy figure slowly appeared in the mirror. Jiang Siruo washed her hands as if nothing had happened, then left and climbed straight into bed. Roommates A/B/C/D: "Hey, Ruoruo, you must have figured it out by now, right? Actually, we're not..." Seeing the red eyes, tails, and scales each of them revealed, Jiang Siruo snapped the carbon-fiber pen in her hand. "No, I haven't figured anything out!" Nobody's going to disturb my studies!
