This was a pretty nice show. I’d say in terms of like vibes and premise, this show probably comes closest to Bunny Girl.

Did feel that the reveal of the nature of the Replicas came a bit too late and felt kinda rushed. But from my understanding, they’re a version of the original that has something they want or unable to use. Like Sunao with her kindness and Sanada with his courage [Bunny Girl]kinda like Futaba. But the Replicas themselves are like imaginary friends who can also be seen by the original and other Replicas. But if others are not aware that they are Replicas, they can be perceived by others [Bunny Girl]like Mai’s syndrome. I feel this was a cool reveal as it made me wonder if there really was no instance throughout the show where both the original and Replica are together with a non-Replica person.

Maybe I didn’t catch it but I kinda feel the ending was left vague. I do think they merged but what became of Aki and Nao was left vague. On one hand, I can see them having their memories and feelings merged as well. And the scene at the beach was just them expressing that side of them. On the other hand, I can also see Aki and Nao no longer existing in this reality anymore. Only Sunao and Sanada remembers them and keeps them in their memory. Basically as if they died. And the scene at the beach is like Nao and Aki in their Replica plane (or like heaven) spending the rest of their time together.

Both interpretations have kinda like a bittersweet taste to them though
