Perfect Marriage Revenge

Having realized that she's returned to a point before her marriage, Yi-joo decides to navigate a different life course. Her stepmother and stepsister, no longer considered part of her familial circle, morph into her most formidable adversaries. She initiates the process by breaking off the wedding with a man more inclined toward her sister, and then she orchestrates a scheme to sow intricate chaos within her supposed family.

Yi-joo comes close to a regrettable choice at her wedding with Do-guk, driven by the realization of Jeong-hye's manipulation, but Do-guk intervenes just in time. The morning after the wedding, Do-guk discovers a note from Yi-joo and her empty room. Meanwhile, Yu-ra views Jung-wook as an ideal instrument for her schemes.

Cho Dong-soo rats out Jeong-hye to the police, and they both get arrested. Yi-joo and Do-guk seem to enjoy their lives until Do-guk confesses that he is the reason why they both came back in time. Meanwhile, a construction site worker hired by Taeja's subcontractor dies on the job. Jung-wook tries to sweep things under the rug.
