Determined to take revenge for her sister, Yu-Ri decides to marry Chan-Yeong. Just then, her first love Tae-O reappears before her.
To repay the kindness of her savior Trevon, Anya Sharp agrees to a mysterious old gentleman's request: to work as a live-in maid for six years, caring for Blake Huber and his young son. During those six years, Anya quietly endures the Huber family's cold treatment and the constant scheming of Blake's ex-wife, Keira. She keeps her head down, waiting patiently for the agreement to end. But when Keira suddenly returns, the favoritism and betrayal from both father and son shatter Anya's resolve. Heartbroken and disillusioned, she walks away the moment her contract ends—and reunites with Trevon who has finally recovered. Only after losing her does Blake realize what she truly meant to him. But by then, it's too late. When the long-buried truth finally comes to light, Blake suffers a life-threatening injury protecting Anya. In the end, Anya chooses to move forward with Trevon, leaving the pain of the past behind.
