By offering her anus, the only chaste thing she has left, she's giving him what virginity she has as an offering to be that pure girl he wants so badly.
They're flawed, damaged, characters but through the process of their ordeal they were able to realign their priorities and come out for the better.
It can be sad if you look at it purely as "MC didn't get what he wanted at the beginning of his character arc", but after his trial he was no longer the naive child he started off as.
It's NTR as fuck, but in my opinion has a lot of the elements that make a story great: adversity, vindication, and a bit of bittersweet without going full-on Greek tragedy.
