So far the chart seems fine to me, with the characters introduced.

Fujitaka? I can never keep it straight.
Fujitaka, yup.

Though I think Toya gets an award for being the only one so far to move on and find someone more age appropriate.
...Well. It'll get complicated.

Probably, they dressed him up like a cute little girl for kicks.
I'm sure they did. Also, CLAMP love to dress the poor Syaorans up in, um, dresses and wigs. You'll see XD

It's not like Syaoran is jealous of Kaho. He just dislikes her because their magic is not compatible, or that's the explanation they give us later.

Kaho has awesome maze solving abilities.
...Huh. I think it's because, I don't know, they're in her house or she knew the solution to that one already. Because later on, someone teases her for her ability to get lost in the streets. Kaho is secretly a klutz :D
