Risa Hasumi is in the midst of divorce mediation. Facing separation for the second time, she holds a strong desire to protect custody of her two children. Having carried and given birth to them herself, she refuses to let go of her responsibilities as a mother, even as divorce becomes unavoidable. She's always had terrible luck with men—every man she's met has been a deadbeat, and her current husband is no exception, plagued by infidelity, debt, and violence. Since giving birth, their marriage has become completely sexless, and their relationship continues to deteriorate. Now that she's taken the step toward divorce mediation, Risa finds herself caught in turmoil—and her mature, married woman's body begins to burn with an overwhelming, uncontrollable sexual desire.
