Nataku is a robot, so Wu Fei is out of luck.
Clearly you're not open minded enough. Nothing will stand in the way of Wu-Fei's love! The true OTP of the series (I think I used that term right...)

Trowa either loves Heero or has the biggest and most concerning case of hero worship ever.
It can't be both?

Quatre loves being cute and huggable(I'm assured he gets his chance at insanity soon)
Insane cackling and everything. It is his greatest moment.
