Gyeong-Sook spent years ruling over her daughter-in-law, Hyeon-Joo, with quiet cruelty, holding fast to class prejudice and the bitterness left behind after losing her husband and only son. To her, Hyeon-Joo, with her humble roots, was never good enough. After her son's tragic death, the two women drifted apart, bound only by shared grief and silent blame. Years later, life throws them into a twist no one could’ve scripted. Both women remarry, and Gyeong-Sook suddenly finds herself in the very role she once looked down on: Hyeon-Joo’s daughter-in-law. Old grudges bubble to the surface, but so do unexpected moments of reckoning. In this strange, uncomfortable new reality, the past refuses to stay buried, and both women are forced to see each other—and themselves—in a different light.
