Introduction: Suppose, in a university dormitory, there is a rotten boy, a straight boy, a shoujun, and a bastard. Is this dormitory really awesome? A909 This is a very peculiar dormitory. Its geographical location is at the far end of the ninth floor. Generally, few people come to visit it because it is far enough away. This is a four-person dormitory. There are four beds, all of which are upper bunks. There are four types of people, and their attributes are rotten man, straight man, shoujun, and gongjun. Just, they spent a happy time as college students in this dormitory, which was a time full of sexual intercourse and love. (Since I am incompetent in naming, I will promote whoever I see.)
