As soon as he arrives, he's welcomed to a downpour of rain and seeks shelter at an abandoned shed, where he meets a young girl. They come close to one another to stay warm, but soon this results in passion taking over.

Afterwards, he ends up staying over at her house and she introduces herself.

"My name is Isshi Mizuki".

That’s when he realizes that her last name and her smile were similar to his first love, Isshi Mizuho, whom he wasn’t able to confess to twenty years ago due to his timidness. Nozomu, who's now aquanted with her daughter, has once again fallen in love in his hometown.

His new work is now planned.

I'll do what I couldn't do back then. Say what I couldn't say back then. The continuation of youth that I let slip away - Will be with her.
