As you know the manga is still ongoing (and the couple ending up together is always the last thing that happens in a story). At first, after seeing the anime I was really worried about Wolfram ending up with a broken heart, but as I read the manga, novels and interviews to Takabayashi sensei, I realized that there's no way that Yuuri will end up with anyone else but him. Why do I say this? Very simple, Takabayashi (the author) has said that her favorite character is Wolfram. And what kind of a sadist must you be to see your favorite character end up alone and brokenhearted, being that you, the author, are the almighty creator of the world he lives in? Wolfram has said many times that he will always stay by Yuuri's side, so there's no way that her favorite character can be happy if it is not with Yuuri. So, ta-dah! This is to me the ultimate proof that no matter how many MORE years it takes they will end up together. Rejoice!
i reallllllllllly hope so,i love wolfram
say everyone does yuuri end up with walfram? i wish it does
