Takashi is on a business trip with his colleague Suzuki, who has been entrusted with a business negotiation. The manager of the client's company is a woman named Kanaya, who is sexy, busty, and beautiful. However, once the negotiations begin, Kanaya is relentless in her aggressive attitude and makes harsh criticisms. As expected, the deal fails. That night, the two of them are boiling over with Kanaya's attitude and decide to go to a soapland to cheer themselves up. There, Takashi asks for the number one girl at the store... but to his surprise, it is the beautiful manager he met that day, who greets him with three hands folded.
