That epilogue seriously did Yori dirty in a way that feels completely at odds with the rest of the story, going all the way back to Mari hugging her before any identity stuff happened. The ending where Mari becomes just "Mari" again, goes back to calling her by her last name, and then distances herself? It feels completely artificial to me, like an editorial decision to make "her" "normal" for a "happy" ending, and it just ends up ringing false to everything we know about these two people.
