Working for a demanding company, I'm asked by my boss to stay late again today—but unlike usual, I'm not discouraged. Tonight holds a special turn of events. I've ended up alone with Satomi-san (Momoko Isshiki), a married female colleague who's the office's beloved Madonna. She's beautiful, flawless at her job, and always maintains a calm, elegant demeanor. Seeing this all-nighter as a once-in-a-lifetime chance, I confront her about how she truly feels. And just as she tries to leave by the last train, overwhelmed by uncontrollable desire, I pull her into my arms... The end of work becomes the beginning of something new.
