Hiya

I read a fic a long time ago and don't remember what it is called. It went something like this:

Draco pulls a prank in the library and accidently bumps into Hermione and get stuck in a secret room. They get drunk and start decorating the room and singing Christmas songs. They almost kiss but Harry, Ron and Dumbledore rescues them. They start to get in a secret affair, but Harry finds out.

Can anyone help me? It would be greatly appreciated.

Thanks
