Ronin's Saito falls in love with the married woman “Violet” live next door. He cares for Saito and serves dinner, assists with medical examinations, and is a beautiful woman with outstanding style. There's no reason he shouldn't love Violets. However, although I really longed for my husband to be living a happy family with Violet, there was also a contradiction that I should not be like that. One day, screams came from Violet's house during the day, Saito rushed to help.
