A retro coffee shop with a reluctant master and an easygoing part-time worker serves as the warm, nostalgic heart of this omnibus collection. The first story introduces Eitaro, a high school senior stumbling home after a tough mock exam. He collapses from exhaustion and is reluctantly brought into the café by the meddlesome waiter Satsuki. There, under the gentle gaze of the master, Eitaro vents his anxieties about exams and his uncertain future, even as he refuses the melon soda offered to him. But later, a chance re-encounter with Satsuki moves him unexpectedly, hinting at a budding connection.

Each subsequent chapter follows a different set of characters whose lives intersect with the same café. A student delivering café goods finds herself drawn to a customer. A rainy afternoon leads to an unexpected conversation. A coffee‑jelly fortune‑telling session reveals hidden feelings. Through these vignettes, the café becomes a stage for small, everyday dramas—moments of humour, quiet comfort, and gentle healing. The stories are self‑contained yet subtly linked, with the café’s familiar atmosphere and its staff (the no‑nonsense master and the energetic Satsuki) tying them together. The collection explores themes of self‑discovery, kindness, and the unexpected connections that arise over a cup of coffee, all delivered with a light, whimsical touch.
