Mori is the chief flight attendant of an airline, and she is tasked with training the new employees joining the company. Hashimoto, although having joined the company four years ago, often makes mistakes and has to attend Mori's training course for new staff. Due to recently being hurt by her boyfriend, Mori has a strong dislike for men. She continuously scolds and imposes harsh punishments on Hashimoto, while she treats the other female employees with great care and gentleness. One day, while browsing the internet, Hashimoto comes across a website advertising aphrodisiac drugs, and she decides to order some to have on hand just in case. And an opportunity truly arises when their superior assigns only Hashimoto and Mori to handle an entire flight. Although Mori is very unwilling, she reluctantly agrees. Since they have to wait for the return flight, they both must stay overnight. Unfortunately, due to a booking error, only one room is left available, and since it's late, they can't find another room, so Mori has to share a room with Hashimoto. Taking advantage of the golden opportunity, Hashimoto spiked Mori's drink with aphrodisiacs, making her body incredibly sensitive. He was determined to pay back for all that he had to endure during this time...
