The author of this (시니/SiNi) actually worked at a fire department for some time and has lots of experience with death (I heard this in an interview). He made another series, “about death.” Its really amazing and full of wisdom and will really make you think (words still cannot even describe how brilliant it is, actually). He is by far one of the most introspective webtoon authors I’ve ever seen so I’m thrilled to find out he has another series going. I’m expecting this one to get really deep as the story progresses.
