Umi is a highly capable and beautiful manager who oversees her subordinate, Aizawa. Despite her professional success, Umi suffers in a toxic personal life, trapped in a volatile relationship with a partner who is both abusive and neglectful. During a business outing, Umi’s low alcohol tolerance leads to a state of complete intoxication. When she becomes disoriented and attempts to undress in public, Aizawa intervenes, bringing her to the safety of his nearby apartment to prevent a scene. Mistaking his home for her own, Umi begins to undress, and Aizawa, unable to resist the sight of his stunning boss, seizes the opportunity to initiate an intimate encounter while she is vulnerable.
Despite the circumstances, Umi does not hold a grudge against Aizawa, acknowledging that her own lack of restraint led to the situation. As her partner’s behavior continues to deteriorate, Umi finds herself seeking comfort in Aizawa’s company again. They return to drinking, which leads to a repeat of their previous encounter. This recurring intimacy creates a complex emotional bond between the pair, serving as a desperate escape from the pressures of Umi’s reality. The tension between her professional life and her personal turmoil creates a charged atmosphere where professional boundaries are completely dissolved in favor of raw, impulsive desire.
Eventually, Umi’s partner attempts to reconcile, promising to change and offering a future of marriage and domestic life. Choosing to move forward with her life and leave her career behind, Umi decides to quit her job. Before she departs from the office for good, she and Aizawa arrange one final, private meeting at his home. This last encounter serves as a bittersweet farewell, allowing them to consummate their secret connection one last time as a final memory of their time together before she moves on to a new chapter.
