Saigo is a beauty cream salesman.
He is a pathetic man who fails to achieve results in sales and disappoints his wife in bed.

One day, Saigo rescues a cat being bullied by some young men and buys it a hamburger.

"Thank you, uncle..."
He thought he heard a voice, but there was no one behind him.

But! Then Saigo completely changes!
He gets into bed while promoting the effectiveness of his beauty cream! He wakes up his sleeping wife and begins an intense sexual encounter!

Saigo is a completely different person, both day and night! This is a man who can do his job!
