lol RimaSenriLove :P But I have to contradict you there. Zero may not have done anything significant for Yuki yet because he simply believes he doesn't have the right to. He feels that he shouldn't get all this love and care from Yuki. This guilt stemmed from his uncontrolled bite of Yuki, which led to the events that we know of later on. With Yuki offering Zero her blood, she is in fact willing to be a vampire's victim and Zero feels that he is not worth her devotion, being the 'monster' that he thinks he is. And besides, Zero's tsundere behaviour at the start was instigated because Shizuka bit him four years ago. Because of this, Zero has a general hatred to all vampires because she killed his parents. Therefore he isolated himself from everyone because... well would you be in a happy mood if a vampire killed your parents, took away your little brother and messed up with your destiny?

Will continue later. Meanwhile, discuss away - Tsuminohime is intrigued :D
