Professor John Carter taught with passion and a deep love for both medicine and the teaching profession. He took his work very seriously and had no patience for mockery, laughter, or joking around in his classroom. He was not particularly friendly toward his students and rarely granted second chances—offering them only when truly earned. He lived alone in an apartment near the university; his life was simple: he would go to the university to teach and handle administrative duties, then return home. Divorced and childless, he had no intention of having children, as he was already surrounded by young people at the university. He began to fall for Lila, but knowing it was inappropriate, he tried to avoid her so she wouldn't notice.
