Mikkakan no Koufuku

Three Days of Happiness is a light novel by Sugaru Miaki, who also writes under the pen name Fafoo. The work is a refined adaptation of a story originally serialized on the Japanese textboard 2channel. At its core, the narrative explores a haunting premise: the existence of a mysterious shop where individuals can sell the remaining years of their lives. When the protagonist chooses to trade away his own future, he is forced to confront the profound and unforeseen consequences of that irreversible decision, setting the stage for a deeply introspective journey through the final days he has left. Accompanying the novel's official release was a short companion piece titled I Say A Little Prayer. This supplementary story expands upon the world established in the main narrative, offering readers additional context and emotional depth. While it touches upon certain elements from the primary plot, it carefully avoids revealing any major spoilers, serving as a thoughtful complement to the central tale rather than a distraction from it.
