Kiyoko, a thirty-three-year-old bank employee, believed her wedding was just around the corner—until her engagement is abruptly and unexpectedly called off. Left heartbroken and adrift, she finds solace in an unlikely Samejima, her strict superior and workplace nemesis. Seeking comfort from her loneliness over a few drinks, the evening quickly spirals out of control. Before she realizes what is happening, Kiyoko ends up in bed with the normally unapproachable director, swept away by an intense and passionate encounter that leaves her overwhelmed by sensations she never imagined possible. Assuming their heated night together was nothing more than a fleeting, no-strings-attached mistake, Kiyoko prepares to move on. However, her world is turned completely upside down the very next day when Director Samejima makes a shocking announcement to everyone: they are now married. What begins as a moment of drunken vulnerability instantly transforms into an unforeseen marriage, forcing Kiyoko to navigate a sudden, intimate relationship with the one man she least expected to become her husband.
