Is friendship between men and women really possible? This project monitors and thoroughly examines the eternal theme. Two friendly office workers, both male and female, who say they are bound by a strong friendship, participate in a monitor program called "If you can spend the night without doing anything, you'll win 100,000 yen!" No matter what happens, they'll never become a couple! They boast! However, a "aphrodisiac" has been secretly mixed into the female employee's drink... Will the male employee be unable to resist the female employee who can't hide her desire and asks for his dick and have sex with her...?
