He is the most serious class president in the grade who loves his old man's teacher when he retires.

From the time I was old enough to remember, I've loved old men who were about as old as my father. My father was so strict that he couldn't be spoiled. It could be a reaction to that. My homeroom teacher, Mr. Sayama, is kind and his tired expression is incredibly cute... and the teacher has become adorable every day. I want to marry a teacher...I don't need anything else if I have a teacher.
