I just have to tell you all of this wonderful fic:
Promises to KeepRated: T
Pairing: Touya/Yukito/Yue (well, and S/S, although Syaoran isn't present at the moment)
Summary: Ten years after the CCS events, Syaoran travels to Hong Kong over Christmas in urgent business, leaving a pregnant Sakura behind, who gets to stay at Touya and Yukito's place for the week. Mostly Touya's POV.
Why I think you should read it: The characters are absolutely dead-on, and to that, the author points out some interesting things about their personalities and their relationships with one another. It's a good mix of fluffy cuteness, humour and drama, with a pinch of angst to make it complete.
It's my favourite fanfic ever, do give it a try!
