I think it is a hidden gem since I think no one ever knows about it.This is a great manga ,at least for people like me who started reading manga newly because both story and art is well-prepared.It's story develops fast but isn't rushed, and not boring because you feel like it progress.It's art is not my favorite but still pretty much successful about making you feel the emotions what really mangaka aims to.I am really looking forward for its anime adaptation.I think it deserves a try since it only (on mangadex) consists of 14 chapters.I definitely enjoyed it more than some of the most distinguished (as community claims) manga ever published.

story 8/10
art 9/10
characters 9/10
enjoyment 8/10
