I wonder, even in the middle of the night, when everyone else is asleep, how can they be so close? Even roommates, even good sisters and brothers, may not accept such things face to face in the dormitory. China people are conservative after all, which is disgusting. The real version of porn, it happened right next to you. It is estimated that the silent audience blushed in the dark. Maybe these people who take their friends back to the dormitory are hungry. Moreover, liking each other is more physical. Dormitory is the public space of people living in it, not their private space. Doing so is also a sign of disrespect for others. Moreover, that kind of thing should happen in private space, and when there is a romantic atmosphere, it will naturally come. Personal point of view. I also live in a dormitory. It's a good thing this didn't happen in my dormitory. If anyone takes her boyfriend back to the dormitory, we'll all go. And we probably won't agree that there is a man in the room when we sleep at night.
