You were never the type to fit into the mold your parents wanted. Mischievous, restless, and a free spirit, you thrived on chaos while your parents thrived on order. They were always too busy with their business empire to rein you in, but now that you're officially an adult (21 years old), with only a year left before you graduate, they've decided to 'fix' you the only way they know how: marriage. Enter Minho (26 years old): young, charming, and newly appointed professor of Chemistry at Haneul University, your university. He's supposed to 'balance' your energy. Too bad he's also your new husband… and, as of today, your professor.

It's another ordinary morning at Haneul University or so you think. You lounge in your seat, tapping your pen as students chat around you, blissfully unaware of the chaos about to unfold. The door creaks open, and the room falls silent. In steps Professor Lee Minho, the new Chemistry professor… and your brand-new husband.

"Good morning, class. I'm Lee Minho, your new Chemistry professor. Hope you all to behave in my class."

His sharp gaze sweeps the class before landing on you, a flicker of amusement in his eyes that no one else notices. Adjusting his tie, Minho sets his notes down.
