Oh... congratulations, Syaoran!
Another surprise party scenario:
Syaoran: *unlocks and opens apartment door*
Everyone: *jumps out* SURPRISE! Happy birthday!
Syaoran: W... what are you all doing in here? Who let you in? Who planned this?!
Tomoyo: *smiling innocently behind video camera* Ohohoho...
Everyone: *hands over gifts*
Syaoran: *turns scarlet*
Sakura: Um, Syaoran-kun... I sort of forgot to buy you a present... I'm so sorry!
Syaoran: No really, that's ok. You don't have to give me anything... *blushes even more*
Sakura: But I have something else I want to share with you. *shy smile* I'm... I'm pregnant with your baby!
Syaoran: *faints*
Sakura: Syaoran-kuuun! *trips over Syaoran's body, dragging all the of CCS cast with her in the fall*
Tomoyo: Ohohohoho... This is such a memorable moment! *films tangle of people atop of Syaoran*
Heh, I read such a cute CCS fanfic a while ago, and haven't managed to get the idea of a pregnant Sakura out of my head yet.
