We have a Wei Wuxian, Lan Wangji and Lan Sizhui at VoidTreckers (voidtreckermods)! It's a variably-paced game where characters are pulled into working as heroes/disaster relief for worlds in danger, in-between which they're living in relatively close quarters on a train hurtling through time and space. The pace is slow in downtime and medium-fast on the missions, although mission tags can go on for a while and there're a lot of different tasks and stages to the scenarios so there's no penalty for taking your time.

Mostly I'm commenting because they have a medical carriage (with surgery and full equipment and large written warnings about not using any of it unless you're senior medical staff) but no senior medical staff, and that's genuinely tragic.
