Reveals won't be until mid-January, so that gives you time to catch up and read/comment while the stories are still anonymous. If you guess what I wrote, you win...the No Duh! Award.

The Twelve Ways of Christmas - Multipairing - a future Christmas for the tennis boys and tennis girls, happy, sad, funny, smart, and interesting.

Don't Hate the Player - Inui/Yanagi - Smooth and lovely Data Pair!
