Fogged Up Windows and Dancing

[blueinterlude]

 Hello, I'm a first time poster but a long time follower of this place, but I've gotten to the point where I really just can't find this story. I don't remember where I read it, but there was a story where either Remus or Sirius drew things in the fogged up window, at night I think, when the others were asleep, and that's how the other found out they loved them. At least, I think that's how it went. I think it may have been that one of them was gone, and they were counting the days they were gone? 
But again, I could be confusing two as well.

Also, I really enjoy masquerade themed fics. I've read the ones that have been recommended here before, but I can't see to find any more good ones. Any suggestions there?

Many thanks,
Lily
