Ozawa's company was also a business partner, but the contract was finally terminated. At that time, Rinka learns that Ozawa is recruiting for a secretary and heads for an interview. However, the person they were looking for was a mistress called a secretary. It was a foolish story, but Rinka, who had a large amount of debt and was hungry for love more than anything, accepted Ozawa's lewd kiss that tested her resolve.
