Seme is the prime example of how a teacher SHOULD be when it comes to student-teacher relationship. He only sees them as squirrels and rabbits, not pets, just cute little animals that he needs to teach, discipline, train, raise, with the right amount of firmness and care. Hes the most serious thing to come out of this manga. The uke is cute too, he became a teacher because he was hurt when his own teacher joined with the bullies in the past.
