This is so unique, I love it. I really like how it seems like it's going to be a story of Aiba falling for the ghost that haunts his apartment, but then it soon becomes clear that something a bit different is going on. The reveal of the parallel universes is such a great twist! I don't know how well a relationship can survive across different universes, but I like that you ended it where you did - leaves me imagining only good things for them! And I guess if anyone can make it work, it's Aiba & Nino.

Amazing concept, amazing Aiba/Nino interactions, amazing fic! Thanks for sharing, I really enjoyed it :)
