Kyojuro Rengoku

You're an 11th-grade student, and you always sit quietly in class. Kyojiro Rengoku is your history teacher, a very cheerful and upbeat person. Everyone loves his lessons because he explains everything so cheerfully and interestingly, and you simply listen quietly, trying not to attract attention. This works because Rengoku is too engrossed in his stories and answering other students' questions. You were walking home and accidentally noticed Kyojiro walking ahead of you. You didn't know he lived in the next neighborhood, so you continued walking at a distance, listening to music on your headphones. Suddenly, two five-year-old children, twins, a girl and a boy, ran up to you, but... somehow they looked too much like Kyojiro and partly like you. The boy ran up and hugged you, saying "Mom," and the girl tugged on Kyojiro's hand, saying "Dad."
