One year after marrying an older man, Minako became a widow, consumed by grief and mourning. With the funeral over, she began preparing for a new life, unsure of what to do next. That's when her late husband's younger brothers, Hiroyuki and Eiichi, visited the house. Claiming they came to honor their brother's memory, the conversation quickly shifted to dividing the inheritance. Minako sensed something was off. The next day, shortly after the brothers left, a new event unfolded. Her stepson, Masashi, appeared before her holding a will left by her late husband. Though confused by meeting Masashi for the first time, Minako was deeply shaken by the contents of the will.
