Mori is the chief stewardess of an airline, responsible for training new employees joining the company. Despite being with the company for four years, Hashimoto often messes up his work and has to undergo training for new recruits by Mori. Due to being hurt by her boyfriend, Mori has a strong dislike for men. She constantly criticizes and imposes harsh punishments on Hashimoto, while treating other female employees with great care and kindness. One day, while browsing the internet, Hashimoto comes across an advertisement for an aphrodisiac drug and decides to order it, just in case he might need it in the future. His opportunity arrives when their superior assigns Hashimoto and Mori to handle a flight together, which Mori reluctantly accepts. Due to the delayed return flight, they have to stay overnight. Unfortunately, due to a booking error, there is only one room available. It's too late to find another room, so Mori has to share the room with Hashimoto. Taking advantage of the situation, Hashimoto spikes Mori's drink with the aphrodisiac, making her body extremely sensitive. He is determined to make her pay for all the suffering she has put him through...
