Some fans of the original manga have noted that the anime adaptation condenses several scenes, such as early interactions between Ryuuki and his friends, to fit the OVA's runtime.

The story follows (sometimes referred to as Yuuki in different translations), a young boy who has been raised by his older sister, Reiko , following the tragic death of their parents. Ryuuki is a quiet boy who admires his sister deeply, but his life takes a surreal turn during the summer holidays.
