Synopsis：After a wild one-night stand, Su Wanning was shocked to discover the man she’d slept with was the new substitute professor at her university!

I didn’t know you were my professor!”He stood, looming closer until her back hit the wall. “Now you do. And trust me—I’m not that easy to pay off.”
