In the Sacred School

Teacher Han Se-ah has a tough life. Students give her a hard time, the principal yells at her, and a rich junior uses her.

One day, she catches that junior cheating with her boyfriend.

At the same time, her first love from high school, Shin Sunghan, returns as the new chairman.

“Why are you the one avoiding them? Why didn’t you confront them?”

“Why are you talking so casually? I’m a teacher here. Show some respect.”

She wants to ignore him, just like the time he left her without a word. But he’s still the same—doing whatever he wants.

“Revenge? Want my help? I’ll do it if you want.”

He keeps provoking her—with a plan to get back at her ex.
