Noooo not the cliffhanger, I'm guessing the next chapter or if there's another after it will be the last one
This manga was great, it was really an eye opener, lately I've been searching for manga/anime that look deeply into these kinda of things, even if there wasn't an inherently fairy tale ending (which in my opinion makes it all the more better)
But I'm happy it's ending with a lesbian wedding, that's pretty cool
