On the night of August 19, 1980, a bus was set on fire by the vagrant Hirofumi Maruyama at the Shinjuku West Exit Bus Terminal. In the burning flames, Mitsuko, who was exhausted by her affair, suddenly thought of suicide. As a result, she escaped too late from the bus and suffered a serious injury. From there, she was hospitalized for a long time. As she gradually recovered, the wife of her affair partner, Soroku Sugihara, died of cancer. Soroku proposed to Mitsuko again, and they lived together. Due to Soroku's mounting debt, they decided to flee to Tojinbo. With the desperate persuasion of her acquaintances, Mitsuko regained her desire to "live again."
