Oh man Xiao Xiao and Shian are cute little kittens. Shian doesn't seem like the college type. Even if he does go, I think he'll be like Xu Qin and resist the office job typical route. Shian would make a good day laborer, or even a cop like his father-in-law. Something where he doesn't need to think too hard. Something that keeps him physically active so he doesn't start peeling the wallpaper out of boredom. Speaking of physical activities, they were absolutely making out in there. Stopped short of going all the way, though.
I predict a Xu Jin arc where she finally meets a boy on her level, and they'll both be wierdos. Maybe an Otaku who is surprisingly ripped cause he does the One-Punch Man workout, and an exceptional cook because he got really into Food Wars. They'll have a meet-cute where they argue about competing for top grades, she'll kick his ass, and he falls head over heels.
