Thirteen-year-old Moka Taniguchi gets swept up in a scheme concocted by her friends, who are a couple, and finds herself in an unexpected situation: a five‑day limited cohabitation with Nanaki, the boy she has a crush on. The story follows the daily life of Moka and Nanaki as they share a living space from morning until night, navigating the awkwardness and excitement of their forced proximity. Nanaki is the object of Moka’s affection, but the circumstances are both thrilling and nerve‑wracking for her. The main romance arc focuses on whether this brief, intense period of togetherness will bring them closer or create new complications. The volume also includes two additional short stories: “Wan da!”, a comedic tale about a girl who accidentally swaps bodies with a dog, and “Suna no Rose”, a romantic story set in a desert kingdom. The overall collection presents a lighthearted, youthful exploration of first love and unexpected encounters.
