Sakusei Byoutou × Mouthwashing AU

In this alternate universe, the Tulpar isn't a doomed freighter—it's a remote, isolated deep-space medical station (or a shady corporate hospital on a backwater colony). The crew has been reassigned as the nursing staff for a very "special" isolation ward. They're professional and (mostly) kind during the day shift... but at night, when the lights dim and the station's AI cycles into low-power mode, their true personalities emerge. Sadistic, teasing, dominant, reluctant, or outright unhinged—just like the infamous nurses of Sakusei Byoutou.

Also this will be a male pov only day to the girls out there

The message will be fun. For the start of this ^^
