She has ever since she was rescued when she was 5
Yuuki does love Zero but she has to marry her brother Kuran Kaname since purebloods can marry their own sister or brother-the same thing happened with her parents and she will marry sadly Kuran Kaname but she does love him.
In the anime "Vampire Knight", Aidou Hanabusa does have romantic feelings for Kuran Yuuki, but she is in love with Kaname Kuran. Ultimately, Aidou respects Yuuki's feelings and supports her in her relationship with Kaname.
No one knows kaname's real parents because kaname is not yuuki's real brother,yuuki's real brother was killed by rido kuran,In the second season of vampire knight,episode 7,kaname bit yuuki and yuuki believed that kaname is her elder brother but he's not and yuuki doesn't know that.
Yuuki Kuran in "Vampire Knight" stays with her adopted brother Kaname Kuran, who is also her love interest in the series. They were raised together in the Kuran family household after Yuuki lost her memories as a young girl.
Okay so in the end Yuuki goes somewhere with Kaname Kuran and Zero...is all alone. :(
im not sure exactly what happens i get my chapters mixed up, but i think depending on which part of the manga your at if its after the vampire ball kaname gives it back to yuuki, if it is when yuuki and kaname go to the kuran house, kaname keeps it, if its when zero gets his power, kaname gets from yuuki im not sure exactly how but one moment yuuki's best friend gives it to her and the next kaname has it. hope i helped! :)
Ruka has strong feelings of love, and loyalty to Kaname Kuran. Kain is in love with Ruka, but she doesn't notice of course. Kaname s in love with Yuuki obviously. Kain is happy if Ruka is happy, and only tries to help her, but suffers knowing that she won't fall for him. But, I believ Ruka will stop putting herself out there for Kaname, only to be crushed by his cruelty ( Yuuki gets that from Kaname) and finally realize Kain's feelings, and soon feel the same. (=
In "Vampire Knight," Yuuki chooses Kaname Kuran as her romantic partner. They have a deep and complicated history that ultimately leads them to be together.
In the series "Vampire Knight," Yuuki Cross ultimately chooses Kaname Kuran over Zero Kiryu. This decision leads to a strained relationship between Yuuki and Zero, but not necessarily a direct dumping.
kaname loves yuuki as something more than a sister (READ THE MANGA)
because he wants the blood of yuuki the adored daughter of haruka and juuri..because juuri's blood taste like the blood of yuuki...
She is in love with both, but she loves kaname more and she chooses him in "Vampire Knight Guilty". Kaname is the person who she actually loved, and always been with so she does love kaname more, kaname is in yuuki's most important place in her heart. Zero is in her heart as well.
