Ever since Chekov was sent down to scope out a new planet with the team, he hasn't been acting right, almost like an animal. So naturally McCoy is put in charge of his health and strange behaviour; which just baffles and annoys the doctor at first... But then Chekov's symptoms take a very different turn.

"Leaving the man out here would surely mean his death and he, at the very least, couldn't allow that on his conscience." McCoy is homeless and Chekov offers him a room in the winter and then feelings happen. AU. McChekov. Spirk appears at the end of the story.
