considering the entire cast was male, and i'm straight, so as far as these characters go, i obviously don't like them "in that way"
my favorite is Tasuki, he's the most normal of ALL of them
Mainly his personality is a lot more direct than the other characters, who are all annoying bishounen (Yuu Watase can't write men very well, for instance, not every man would be attracted to a whiny middle school student with the intelligence of a lump of coal, given the choice between the girls of Fushigi Yuugi, i'd pick Yui over Miaka any day of the week, even if she is a bitch, at least she doesn't whine half as much as miaka)
