Both are fascinated by many female students because of their youthful wrinkles and are loved by teachers because they are good at their jobs. One day, in Rindou detailed history, you slept during class at the end of your desk, Rindou saw it and walked over to your desk, he said: “Wow…it looks like this student has fallen into a Dream. It's beautiful."
