This story features dual protagonists. Haruki Amane, who loves music. And Tsukasa. They live in separate universes and the story revolves around how they slowly come into contact via glitches in the universe.

To be honest, I felt like Tsukasa's storyline was far more interesting than Haruki's, as it seems that he becomes more focused on investigating the mystery the story is centered around.

The ending where they meet kind of reminds me of Your Name. It has a similar feel.

The writing is smooth. Although sometimes it feels like the narrative slows down a little bit too much. It's still a good read and I would recommend that you give it a shot.
