I prefer Zero. The reason آپ 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 گیا پڑھا مرتبہ on the world, making it seem darker overall. آپ feel like death will creep up on آپ at any time and wonder why آپ don't cause it yourself. He's not cold یا anything, just upset about the past. So I partially understand what he goes through. When آپ 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 love most. He hides his feelings and wear a mask in front of the world only for the sake of Yuki. His love 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!!
