I want more friends for He Xuan too, even if he's a bum and canonically denies being close to anyone ever even in ghosty times. It does help they're room mates!

But maybe they can fulfill some of those tasks, seeing as he's also born in the summer (or at least I headcanon he's before fall/very late August by some painstaking close attention to details since canon is allergic to birth dates of some characters RIP)

I wouldn't say he works out per say. Also if there's cereal in the house I guess he is "Pours milk into their bowl before the cereal" because that's funny. The wingman sounds also extremely funny but he'd probably be rude about it, though maybe eventually
