The whole serie revolves around the 2 main characters, yamano and tanigawa. Back in middle school Yamano find a missing button for Tanigawa. This is where it reveal that yamano got a crush on tanigawa then fast forwarded to highschool, Tanigawa suddenly approach him then reveal to him that she's dead. However, Yamano then found an alive Tanigawa walking around. The dead Tanigawa then told him that she was killed but don't know when or by who. Yamano then go out to try solving the mystery and the two of them (yamano and dead tanigawa) get to know each other more and more along theway.

As you can tell from the synopsis, it really feels like slice of life meet supernatural mystery but it really just feel like romance slice of life show. I'm not saying it's a bad thing that it turns out like this but it does feel like the mystery element slowly fell off along the way. Like they constantly trying to solve the case throughout but whenever they're getting serious, there's always something breaking the atmosphere and return it back to slice of life.

This serie tries to be a lot but I think the only thing that's decent about it is the romance and since it's a short serie, the build-up feels pretty lackluster because they tries so hard to make the mystery part interesting but what really sold the whole show is the chemistry between the two mc and I'd say the ending did both of them justice by making it emotional.

I really don't really know where to continue this review lol so yeah if you're looking for a slice of lifey romance manga with a little mystery on top then I'd recommend it. It did it job pretty well consider it's pretty short (3 hours read for me).
