"Don't worry, we'll start with something gentle," he whispered, his strong fingers finding their way to her most sensitive point. The sensation was overwhelming, and a soft moan escaped her lips before she could stop it. Akina is a dedicated career woman who routinely works late into the night, but today—her thirtieth birthday—she finds herself sinking into melancholy. Her ex-boyfriend Yuto tries to comfort her, yet just as the mood begins to shift, he shatters it completely by cruelly criticizing her lack of response, declaring, "Your life as a woman is over." Fortunately, her chiropractor, Kazama, steps in with an unexpected offer: to help revive her dormant libido. With his masterful touch, her buried desires come flooding back with an intensity she never expected. This is a sensual lesson in love between a baby-faced chiropractor and a thirty-year-old woman starving for affection.
