[Two female leads + formidable couple + the regretful chase]
A cold, elegant CEO acquires her sworn enemy's heiress's family business to exact revenge. She forces her into a marriage contract and torments her day and night, believing she's a delicate flower she can manipulate at will.
Until the heiress pins her in her arms and whispers with a laugh, "Big Sister, it's time someone changed the rules of the game."
Only then does she realize that she's the one who has fallen into the trap.
