I prefer Zero. The reason anda say he's 'moody' mainly has to do with his parents and the transformation. I had to deal with the thing with the parents and it's really hard to deal with. it changes your tampilan on the world, making it seem darker overall. anda feel like death will creep up on anda at any time and wonder why anda don't cause it yourself. He's not cold atau anything, just upset about the past. So I partially understand what he goes through. When anda connect with his story it's eally heartbreaking. I used to prefer Kaname. That was until I realised he could take away the last of Zero's happiness. As long as he doesn't do that, I have no problem.
Of course its Kaname We cinta most. He hides his feelings and wear a mask in front of the world only for the sake of Yuki. His cinta and devotion towards her is so so sooo Romantic! He is like a tragic but stronger protagonist. He is the perfect lover and he is like Oh-so-hot-yet-calm Vampire XOXO <3!!
