Tsubaki Akanishi, 46, from Mie Prefecture. She married at her parents' urging, but grew disillusioned by her husband's extreme mother complex. Quitting her job as an office lady to please her mother-in-law, she entered domestic life, only to be emotionally neglected after giving birth. Once enjoying a free-spirited OL lifestyle, she felt nostalgic and reconnected with her former lover—an ex-boss with whom she'd had an affair. However, his clingy, lonely behavior reminded her too much of her husband, increasing her stress. Eventually, her pent-up sexual desire and the skills honed through infidelity erupted uncontrollably. Now, all eyes are on her as she faces a life-changing decision.
