Nao is sent on a three-day business trip for a crucial deal that could determine the company's future. She was chosen for this mission because the client's president, Mr. Ozawa, is known to be "interested in women" and has an arrogant personality. Though Nao, a renowned beauty within the company, was brought along to assist with hospitality, her superior quickly backed out once the entertainment began, leaving her completely alone. Forced into excessive hospitality and under intense psychological pressure, she retreats to her hotel room. However, Mr. Ozawa's sexual demands have only just begun, and Nao soon finds herself trapped in his seductive trap.
