After losing his beloved wife, Yukiko, Kyohei drifts through life, stripped of all hope. One day, a young woman suddenly appears before him. "Would you sell me this house? It appeared in my dreams..." she says, before abruptly losing consciousness. Bewildered and shocked, Kyohei waits until she regains consciousness hours later. But something feels off—her manner, her presence. Then she utters words that strike him like lightning: "I'm Yukiko... It's me."
