Hi everybody! I'm looking for an AU fic I read a while ago where Dean and Cas both work for the same company and can't stand each other. Their boss sends them on a business trip together to stay in their client's fancy cabin in the mountains, and they get snowed in there. Feelings come to the surface and, of course, eventually hate turns to love. Thanks in advance to anyone who can help me out! <3

(Not 100% sure about the name-calling and Christmas tags – it's been a while since I read this one – but I'm probably a solid 80% sure that both of those things took place in this story.)
