If these spoilers and others I read are real,then wow.I thought the ending might be bad but I didn't expect it to be this terrible.So after Kaname goes into slumber Yuuki hooks up with Zero,okay.I wonder if she would have still made the same choice if Kaname was there?probably not,sorry but nothing will make me believe she has been in love with Zero more than Kaname since the beginning after all these chapters that shows otherwise.Okay so then after Zero dies,Yuuki sacrifices herself to make Kaname human and..what happened to her kids again?she left her kids and sacrificed herself..great.poor kids.
I wouldn't know myself but maybe the mangaka at least pleased some of the shippers,I guess?seems like that's the only thing she cared about,which is why we're left with this terrible and stupid ending :)
BTW I'm not sad over Yuuki and Zero dying,but the stupid threesome ending is just stupid,well at least Kaname is still alive,I don't know if he'll have a happy life or not from now on but at least since he has no memories,he's free from all his past burdens.
