A Romance Beyond Boundaries

Read manhwa A Romance Beyond Boundaries / A Boundary-Crossing Romance / 선 넘는 로맨스

It seems that the fiancée of Ian’s older brother—whose wedding is just around the corner—is having an affair with a coworker.
Determined to stop the marriage, Ian disguises herself as the secretary to the CEO of the company where her would-be sister-in-law works, planning to gather solid evidence within two months.
“Do you think boundaries exist just to be crossed?”
The man she ends up serving, CEO Cha Jeong-han, has a handsome face but a personality that leaves much to be desired. He constantly gets on Ian’s nerves.
“Yes. Boundaries exist to be crossed, actually.”
With no fear of getting fired, Ian decides to freely cross Jeong-han’s carefully drawn lines.
And somehow, the once arrogant man who thought himself untouchable—
“Did you put on makeup today?”
“What?”
“It looks like you’re wearing lipstick.”
—suddenly starts acting differently.
“This won’t do.”
Jeong-han speaks as he collapses over Ian, his body pressing down on hers.
“What won’t?”
“I can’t let anyone else see the way you just looked.”
“……”
“Cross the line with me—and only me.”
A thrilling romantic comedy with a dangerously escalating curve of emotions!
