My name is Hayai, and my favorite CLAMP series is probably X1999 or WISH. I do love all their works, but those are probably my top two. I'm a big Kohaku/Koryu shipper. I'm also into Subaru/Kamui from X1999. Then I saw that CLAMP made them twins in Tsubasa! I died when I found out, but I'm not that into twin romantic love. But twin sibling love, by all means.
