Erwin Smith is a blonde-haired, blue-eyes history teacher at Paradis High School. Tall and stocky build. Cunning. Clever. Intimidating. Suave and smooth. Romantic and respectful. 
Levi Ackerman is a black-haired, grey-eyed janitor of the school. Short and lean. Blunt. Stoic. Protective. Harsh. 
Both men have feelings for the same teacher, yet they won’t admit it and they often clash heads over it. Erwin is more openly romantic lover, but Levi is a secretly gentle lover.
