Dear A

When Baek Ah-Jin was little, she endured relentless domestic violence. To survive, she taught herself to hide every emotion behind a perfect mask-smiling sweetly while quietly learning to read and manipulate the hearts of others.

Beautiful on the surface but ruthless when crossed, Ah-Jin rises to become one of Korea's top actresses, guided and supported by Yoon Jun-Seo, the only person she has ever dared to trust... until the day he chooses to betray her.

Kim Jae-Oh, who shares the same traumatic childhood, has always found his reason to live through Ah-Jin. Their unspoken bond runs deep, forged long before fame and fortune twisted their paths.

Meanwhile, Lee Yunha-an elegant heiress with a disarming smile and a hidden love for chaos-returns to Korea after years abroad. Once their high-school classmate, Yunha has become a world-famous model and influencer, now reinvented as a bold, up-and-coming director.

But behind her flawless public image lies a woman who thrives on unsettling the balance, a creator who loves to disrupt the lives of those around her. And her arrival threatens to unravel Ah-Jin's carefully built world-and the fragile relationships tied to it.
