- Description from novelbuddy

Her boyfriend and her sister tangled together in the sheets, so she turned around and married the fearsome business tycoon, Gideon Leith.

Not only is she a star in her own right, but she's also a publicist and an entrepreneur?

A super racecar driver? A worldrenown gold medalist designer too?!

Just who is this precious hidden treasure of a girl!!!

She went from being pitifully spurned to a goddess looked up to by tens of thousands of people, and her admirers queued from Jincheng all the way to Kyoto.

Mr. Leith, who saw a certain someone's feminine charm, quickly tucked her into his arms.

“Wife, I need to hide you well. You can only belong to me!”

With a marriage contract forcefully done, he married her, and all she could do was comply, and resent him deeply for that and for all the following misunderstandings they faced.
However, it was already too late when she understood she actually loved him.
