I am so confused and lost and completely thrown off. Based on the current appearance, Miku fits the brides description, but with that picture of them it's been shown that when the girls were younger they all had the same hair color. This article points to Itsuki being the bride, this discussion and the chapters points it it to Yotsuba, The child hood photo points it to being Nino, and appearance's points it Miku. Me and a lot of other people thinks he marries all five of the sisters.

Can someone and I mean anyone clear things up for me, like I will take any of the twins to be his bride but Itsuki.

I don't know if this discussion forum is read or not, but I try anyway. At this point in the manga (chapter 117) with a handful of chapters left, would you like a change of the bride? It seems clear that Yotsuba is the bride, (at least from volume 14 cover...) but I wonder if we can still reasonably think of another ending.

Inasmuch as she has the best overall aesthetic among the five; I can't shake off the feeling that she, out of all the characters, is the least best girl.
