Junjou Christmas (One-Shot)

It's Christmas! Aikawa and the people of Marukawa are throwing a Christmas office party! Usagi gladly goes to the party, with Misaki tagging along. Everyone gets gifts from each other... So why hasn't Misaki gotten one from Usagi? Does Usagi not care about Misaki anymore? It all comes along with an Ugly sweater contest, food, some sake, and a little mistletoe! Saki included!
