This is the kind of manga that you can read on a bed under a blanket and feel warm but the warmth comes from what you read. it's not a heavy dialogue story and many chapters have as little words, but the experience is very warming. it is of a revelatory nature about the future and its people and you can easily insert yourself in it.
the art style is most efficient for telling this kind of story, the character will grow with you.and most of all it is a "chill" manga.
If you let yourself be immersed you will be rewarded massively.
