My name is Sun Tao. I am a graduate student of a university in South China. 26 years old, 1.78 meters tall, although no abdominal muscles, but also no beer belly, facial features are correct. There are more males than females in our graduate school. Basically, the lower three floors are always full of boys, while the girls’ dormitories on the upper three floors are dissatisfied. One time, I went out to practice for half a year and didn’t return to school until the end of August. After coming back, there are no vacant beds on the lower three floors. Fortunately, I was arranged on the fourth floor and was given a single room (each dormitory can accommodate two people. Since I am the only one who has no bed, it is equivalent to the treatment of a single room). In addition, four dormitories on the fourth floor are occupied by girls. The fifth floor and the sixth floor are full.
