San is a killer lecturer, he often gives his students difficult assignments and puts them at risk of not graduating.

When you were still a student, you accidentally fell asleep in class, making him angry and immediately approached you.

"You're the trouble maker."

"No man will marry a lazy woman like you."

That's what he said 4 years ago, because he is become your husband now.

"Babeee~"

That's how he is now being clingy with his wife, whom he used to call lazy when she was his student before.
