When single mom Karina moves into a quiet suburb with her wild four-year-old daughter, she doesn't expect to find trouble - or temptation - living next door. Minjeong, the tattooed, motorcycle-riding bad girl, is the exact kind of chaos Karina promised to avoid. But when Moka worms her way into Minjeong's heart, Karina finds herself pulled into a slow, irresistible burn of stolen glances, late-night confessions, and undeniable heat. Walls will crumble, sparks will fly, and two broken hearts will learn that sometimes the love you fear most is the one that saves you.

The Yu family built an empire on power, wealth, and perfectly calculated deals. Yu Karina is no exception-sharp, relentless, and always in control. To secure their inheritance, all she needs is one final piece to fall into place: Kim Duho's firstborn daughter agreeing to marry her brother. Winter, the ever-elusive heiress, is anything but easy to persuade. She sees through Karina's every move, meets her sharp wit with an even sharper tongue, and makes it painfully clear-she has no interest in being part of the Yu family's schemes. But Karina doesn't accept losses. She negotiates. Manipulates. Wins. And Winter is just another deal waiting to be closed. At least, that's what she tells herself. As secrets surface and time runs out, Karina finds herself caught in a dangerous game-one where the lines between manipulation and genuine desire begin to blur, and falling for Winter might cost her more than she's willing to give.
