Ling Yan, a otaku college student who can be seen everywhere, like other otakus, he has hardly bought any formal clothes or sneakers; he wears his dear "nest" all day long and moves around the dormitory like a snail. He wasn't too dissatisfied with this kind of life, but unfortunately, it didn't last long; a roommate in his dormitory who liked illegal racing forcefully pulled him out at night. As a result, Ling Yan, who had not been out for two years, died very casually during this memorable outing. But when he opened his eyes again, what he saw was a black muzzle and himself wearing a white gauze skirt with long hair.
