Mizuki is a ghost, and meets Misao, a girl who lives in Mizuki's old house. She's the only one who can see and touch Mizuki. Even though they cant age together, they still spend their lives together
that was really nice, I'm glad it had a nice ending, though since im twisted i kinda wanted it to end with misao getting married and the ghost girl just watching her from a distance, pained with unrequited love.
