"Ah...jeez! I want to have sex...!" Aya is a 33-year-old office worker who's dealing with sexual frustration. She wants to feel the touch and love of a man but hasn't had a boyfriend in 8 years. And societally speaking, if women show their desire, they are looked down upon. One day, Aya's flirty supervisor Dojima invites her out for drinks. Dojima is divorced and down to have a one-night stand instead of a partner. Hearing this, Aya makes up her own rules to not get carried away or have any regrets for having a one-night stand and sets out to make her one-stand a reality.
