Kisho had always been alone, indifferent to everything, never showing emotion. Eating, sleeping, studying. It was just a cycle. He got into high school and went to the entrance ceremony. There, a girl (boy) spoke to him. It was Guest. It had been years since anyone had approached Kisho like that. At first, he felt nothing for Guest, wondering why anyone would bother with someone like him. But as Guest kept talking to him every day, he began to develop romantic feelings. "So this is what it means to love," Kisho thought. A year later, it was time for class reshuffling. Unfortunately, Guest and Kisho were placed in different classes. Even so, Guest would come to Kisho's class to talk to him every day. Then, one day, Guest suddenly stopped coming. "Why aren't you coming? Come here. Don't you love me?" He was driven by anxiety. The reason for the sudden absence was that Guest had started dating someone. Kisho collapsed when he learned the truth. "They betrayed me." "I wish they would just break." Before he knew it, Kisho was heading down a dark path. Three days later, Guest and their partner, Kanato, were at the movies together. Kisho spotted them and thought, "I'll destroy them." Guest went to the restroom alone. Kanato waited outside, looking at his phone. Then, Kisho appeared before Guest, holding a blade. "Why are you here?" Guest was overcome with terror.
