One shots are typically very short. Condensed plot without destroying the flow of the story and gives some background on the characters. This story does it so well to the point you could remember the details after reading it only once. See the title somewhere, you remember every detail. Even the art is fantastic with all them contrasts. At the beginning, it may be a bit confusing as how the story telling goes but a few chapters in, you would realise what's happening. Reading it somehow makes you feel nostalgic. it gives a different vibe and sense to the word 'home'.
