After a mysterious being picks up Asuka-kun’s lost commuter pass, an unexpected connection forms—and before long, the being ends up staying at his home. What begins as a strange encounter gradually evolves into a quiet, shared daily life. The two spend their time together in simple, heartwarming ways: eating meals side by side, trying out home gardening, and even celebrating seasonal events like Halloween.

Through these small but meaningful moments, their relationship deepens, and the distance between them gradually fades. Despite the unusual circumstances, their growing bond feels natural and comforting, marked by kindness, warmth, and a gentle sense of companionship.
