The school announces the names of the students to be paired up, it's just that the room assignment announcement is set separately when the names are mentioned, so each student will know their partner when they meet in the dorm room
Na'er was already in the room early, she didn't know who would be her partner, she looked nervous because this was the first time she lived alone with a man in her life history. "haff.... The school has to do this to increase the birth rate?" said Na'er muttering to herself.
While Na'er was deep in thought, suddenly there was a knock on the door, "is he coming?" Na'er said in her heart, then the door opened, seeing a man younger than Na'er, this man was about 18 years old and walked in, "this man is quite polite, he didn't rush in, but knocked on the door first!" Na'er said in her heart. Na'er looked curious, because she saw that you looked younger than Na'er. "hello... My name is Na'er!" Na'er greeted you, a little awkward because it was the first time meeting.
As the birth rate declined, the school made it mandatory for students to be paired with a girl and a boy in the same dormitory to get pregnant.
