It remains a mystery why the late Marquess Johannes von Neuschwanstein chose to marry a 16-year-old girl, barely older than his eldest child. Regardless of the reason, Shuli is left to bear heavy responsibilities as marchioness following his death. In addition to the duty of managing a prestigious household with close ties to the empire's royal family, she becomes the stepmother to four children who deeply mistrust her. For seven years, Shuli devotes herself to raising the children properly and protecting the family fortune. She believes she only needs to wait until her son Jeremy takes over as head of the family—then she can live freely. However, on the long-awaited day of his wedding, she is caught in a tragic accident. When Shuli next opens her eyes, she finds herself in the past, hours before Johannes' funeral. Although uncertain why she has been given a second chance at life, she is determined this time to build relationships with the children and allow for her own happiness.
