Yuki has love for both Kaname and Zero in different ways  and they both love her, but Yuki is partially Kaname's sister. Kaname and Zero have a fundamental antagonism towards each other because they are inherently archenemies. Kaname occasionally expresses a little jealousy over Yuki's attachment to Zero in front of Yuki. Yuki has loved Kaname ever since she was a child during her human life because he was her first memory when he saved her from a Level E Vampire during a blizzard. When it was discovered that she was a Pureblood Vampire , it is also revealed that Kaname is her older brother and that they had pledged to marry each other to be like their parents, who were also siblings. Currently, she is his fiancee. As a human, she fell in love with him and Zero constantly reminds her that she cannot be with Kaname because Kaname is a pureblood vampire.
They have a daughter named Ren Kiryu. Yuki and Zero met at ages 12 and 13 respectively,  when Zero was taken in by Kaien Cross into his home. Yuki immediately took to the young boy and looked after him the night they met, cleaning the emotionally fragile Zero's wounds. Yuki's nature overcame his distance and her presence helped his nightmares to cease.
Zero always had feelings for Yuki, but knowing about her own feelings and crush over Kaname, he decided to hide his own to make her happy. After she decides to stay at Cross Academy to figure out her own feelings, she has to transfer to the night cl If you are under 18 skip or if you just don't like lemons you can skip. I plan doing a last chapter or maybe chapters after this just to wrap it up. Hope you enjoy my pervert side!
