[Machine Translation] Rika's surgery was over. Immediately after the surgery, I was perplexed by the words uttered by the attending doctor, Natsume. What followed was a tepid daily life. It was so ordinary that I couldn't grasp it. A new reality loomed over my bewildered mind. Don't see Rika anymore, you're in my way. On the other hand, Natsume, who had made that decision, had been avoiding me for a long time. On a night when I am on a fool's errand, he tells Akiko about his past. It was a night when the thoughts of those who have lost and those who are about to lose intersected. This is the fourth installment of the highly popular series by Hashimoto Boshi and Yamamoto Keiji.
