Yeah, this may come as a surprise. I think M would compare me more to Ayame Sohma (also of Fruit Baskets) or Suichi Shindou (from Gravitation). I can be excitable and egotistical and annoying! However, I think I'm more like Tohru.
I'm not anime-esque, leggy and uber-thin, but I do have long dark hair :)
Being a geek, I was often the onigiri in the fruits basket:
And, I relate to Tohru's outsider-ness, even though she seems like a pretty normal girl.I'm also really, really nice like Tohru, sometimes dimwitted with niceness. I don't give up on people, and I guess some people will call it naivete. But, I know what I'm getting into.
Tohru loves all the animals of the zodiac without condition. I strive to love the people around me in the same kind of open and sweet way, even if it causes me pain. So, yeah, I think I most relate to Tohru.
