He confesses to her that having a child was not a prerequisite for returning home, and that he just wanted to punish her for abandoning him and their child so he and the kid went through everything just to summon her specifically. They got a two for one when they summoned the guy as well and they hand him off to his fake fiance who then does "THINGS" to him since she only sees him as breeding stock. In the end he basically tells her he's never letting her go again and that she will stay there and have a kid with him and they'll always be together as "punishment". And she comes to the realization that she doesn't need to leave anymore because the original reason she even left him was to be with her mother before she died, and now that she has she actually doesn't have any reason at all to leave. So she's thrilled to stay and get "punished".

Seems like a happy ending for them

I agree that it fits for them and for the story overall. But I think that everybody who is hoping for a revenge arc is just going to be sadly disappointed. ╮(￣▽￣)╭

Yeah but doesnt he make her a cripple and she can never walk again?

Genuinely forgot about that part, but yes. Seeing how she seems to instantly forget about it as well though I guess it's not a huge deal. Cause ya know, that makes sense or something. ╮(￣▽￣)╭
If she's willing to forgive him I'm not gonna get in the way, I think they're both a bit cuckoo for cocoa puffs tbh.
