It seems my brother’s fiancée is having an affair with a coworker.

Determined to stop the wedding within two months, Ian goes undercover, taking a job as the personal secretary to the CEO of the company where her future sister-in-law works.

"Do you think boundaries exist just to be crossed?"

Unfortunately for her, that CEO is Cha Jeonghan, a man as strikingly handsome as he is utterly unbearable. With his cutting remarks and infuriating composure, he makes it his personal mission to provoke Ian at every turn.

"Yes. Boundaries exist to be crossed."

With nothing to lose, not even her job, Ian decides to trample over Jeonghan’s carefully drawn lines whenever she pleases. And slowly, the once-arrogant man who never deigned to look down from his lofty pedestal begins to falter.

"Did you put on makeup today?"

"...What?"

"It looks like you’re wearing lipstick."

'Wait, did his attitude just change?'

"This won’t do."

Jeonghan murmurs as he leans over Ian, his body pressing down like he’s finally given in.

"What won’t do?"

"I can’t let anyone else see you like you were just now."

"....."

"So cross the boundaries with me, and only me."

A dangerously charged romantic comedy, balanced on the edge where boundaries blur and hearts collide.
