Touya is a salaryman. Every day, he finishes his work promptly, goes to the supermarket, goes home and prepares his dinner. After the disaster in his life after his wife Kanako died, his life gradually settled back into this steady rhythm, like a heartbeat. But now, someone is about to interrupt that steady rhythm and make his heart beat faster... Kusuo sells himself for money. The morning after he does the deed for another average salaryman, the guy denies remembering anything. He was drunk last night, but he apologizes and pays anyway. How dare he apologize! Kusuo is just like every other whore... so why is he treating him like this? He is angry and confused, and leaves with the money. But soon their paths will cross again... And how will these two completely different people affect each other's lives?
