Yukito-san is Touya-kun's classmate and best friend. Sakura has had a crush on him ever since they met. The obvious reason for this is because Yukito is very nice, friendly, intelligent, funny (watch the Cinderella episode!!!), polite...and he's SO kawaii when he eats^_^
Yukito, like Touya-kun, is very popular in school. Everything he does makes him more popular than he is at the moment. And, although he doesn't look like it (I HATE people who think people with eyegalsses are weak), he's VERY athletic. He beat the whole Seijou High basketball team by himself (it's not really a game, but...just watch the series), and he's also good at soccer.
Yukito-san is clever. He usually gives advice to Touya when he needs it (not necessarily when he's asking for one). And, though he seems oblivious to the fact that Sakura admires him, he knows what's REALLY going on, and not just what the way things appear to be...And he just HAD to spell it out for Syaoran for the latter to realize his feelings...
"You like Sakura-chan, don't you?"
Yuki is a good cook. He has to be since he's living alone. Though he is usually invited to the Kinomoto residence for dinner, he also brings them food as a token of gratitude.
His favorite flower is the primrose...And his favorite thing to do is...to eat (no surprise there).
Yukito-san LOVES to eat. It's weird because he never gets fat. Amazing, ne? Yukito is very funny...especially when it's lunch time...or dinner... or any of the eight hundred meals he has a day...
Notes about the name:
OK...Let's dissect his name:
Tsuki - moon
shiro - white
Yukito means "snow rabbit". He's Yukito-san to everyone, except Touya, who most usually calls him Yuki.
