Spring had brought Mihana Sumikawa nothing but hardship—her husband collapsed and was hospitalized at the same hospital where she worked as a nurse. Juggling her nursing duties with caring for her ailing husband, her life was consumed by stress and exhaustion. One day, her husband's room was assigned to a new roommate: Fujisaki, her former teacher. Though admitted for routine tests and not seriously ill, Fujisaki was immediately drawn to Mihana’s mature beauty and composed demeanor as a married woman. Unable to control his desire, he soon pinned her down and took her by force. Yet for Fujisaki, alone and aching with loneliness, one encounter wasn’t enough—he began relentlessly pursuing Mihana, pushing their relationship into forbidden territory and leading to intense, repeated creampie encounters between the married nurse and her seductive ex-professor.
