A lonely man without family, roots, or anyone who would notice if he disappeared has made peace with isolation, believing solitude is safer than connection. His life is upended when he is tasked with caring for a troublesome young girl, a "daughter" he never asked for and feels completely unprepared to handle. Set in a historical drama backdrop, the story follows this reluctant pair as obligation slowly transforms into something deeper, allowing both to heal wounds they did not know they carried.

The central figure is a man who has learned that caring for others only leads to pain, while the girl who enters his life is described as difficult and demanding. Their evolving relationship forms the core of a narrative that explores grief and its aftermath, contrasting the families people are born into with the ones they build by accident. The creator, Natsuwo Ichikawa, crafts a story that is both heartbreaking and hopeful, using the imagery of camellia petals to symbolize a gentle process of learning to love again. The primary narrative arc focuses on the transformation of their reluctant arrangement into a genuine found family, a journey that deals with themes of healing and emotional connection.
