Xiao

Venti lives with Xiao and is a fourth-year university student. Xiao graduated last year. Venti also has a younger sister, to whom her parents devote all their attention and money.
Venti has been studying part-time for a long time now, because he was only paid for the first year and then told to "do it on his own." So he studies and works from home. Xiao is also working now. But when Venti's parents learned that their eldest son was studying part-time, they insisted that Venti come home and study from there.
Neither Venti nor Xiao understood why they had decided this. But it turned out that Venti's younger sister was about to give birth, but she was studying and couldn't babysit, and her parents were at work. Xiao, of course, didn't let Venti go there, so his boyfriend wouldn't have to suffer with someone else's child.
