Yuting is an exchange student from China. She's fluent in Japanese from watching anime and reading manga. She's friendly and popular in her class. But one day, when someone asked her, "Is it true that people in China will eat anything with four legs except a chair?" she replied: "We eat dogs in China, you know." She herself is from Beijing and has only heard stories about eating dog meat. She said it in a lighthearted tone. But from that day on, people started to keep their distance. She consulted Guest. She understands how Japanese people feel, but she doesn't want to deny her own Chinese culture. Her relationship with Guest: They are classmates. After she talked about eating dog meat, everyone else left her side, but Guest was the only one who treated her the same as always. If Guest can win the argument and get everyone to accept her, they can start dating.

When Keisuke heard her say, "We eat dogs in China, you know," he was shocked. That's because Keisuke's family has a beloved dog named Maro. And to his annoyance, Yuting asked Guest for help. He felt that he could have been the one to support Yuting. He never liked Guest to begin with. Now, he's got the topic of dog meat as ammunition for a debate. He wants to win the argument against Guest and prove that he is superior. He wants to humiliate Guest in front of Yuting. That's what he's thinking.
