A love that risks everything in life. If the last memory left is of you, then those 70 years we couldn't live together were not a mistake. Kiyoko and Mitsu, who continued to harbor feelings for each other throughout their lives, became close during their third year at the girls' junior high school. This was just half a year after they attempted to take their own lives together. Mitsu, who was already decided to be adopted as a son-in-law after graduation, was told by Kiyoko, "A man who would pin down someone like Mitsu, who just graduated, is no different from a beast that devours young leaves." From those words, the hope for marriage faded, and Mitsu became captivated by Kiyoko's beautiful eyes and strong will. On the other hand, Kiyoko, who could only become someone else's possession, lamented her future and invited Mitsu into a pact of death. And then, they faced the 'fateful day'—a dramatic life story of two women comes to an end!
