Eric, a young man living in a fantasy world, carries the full memory of his past life as a Japanese person. Despite training to become a recovery magic specialist, his healing spells are so slow and weak that his adventurer party fires him as useless. While tending to an injured stray cat, he makes a crucial discovery: his healing magic operates on a delay, building up over time to produce a powerful restorative effect that conventional healers cannot match. Realizing this ability is perfect for running a classic game-style recovery inn, he sets out for a remote, abandoned village to start a peaceful second life.

In the deserted settlement, Eric uses his past-life knowledge to build furniture, cook Japanese comfort food, and dig a hot spring that soothes injuries when combined with his magic. He establishes a cozy inn where travelers can rest, eat well, and have their wounds fully healed by the time they leave. He is soon joined by Marie, a cat-eared beast girl who becomes his helper and companion, along with several friendly cats. The narrative follows his day-to-day efforts to improve the inn, cultivate rice to recreate his favorite staple food, and gradually attract a steady stream of grateful adventurers and locals. Arc by arc, Eric expands the inn and the surrounding village, solving small problems for his guests through a mix of his unique healing skill and practical craftsmanship. The story is driven by his pursuit of a comfortable, self-directed life and the warm, humorous interactions that arise when a former Japanese everyman applies homemade ingenuity and a dash of cheat-level recovery magic to a fantasy world inn.
