Jin Hee has just discovered her relocation resulted from undeserved disciplinary action. Her life is already hard, but it becomes even more so when she comes home to see her mother, Eun Mi, doing something beyond her wildest imagination.
Jin Hee discovers that the only person she wishes to avoid is now her superior. While Jin Hee is on patrol, she receives a radio call about a burglary at an address that happens to be hers. She promptly tries to contact her mother.
Eun Mi notices something odd about a patient and suspects it may be connected to family violence. She discusses her concerns with Jin Hee, who investigates further and realizes she may have limited options in addressing the situation.
Eun Mi, Mi Jung, and Jin Hee have a wonderful time together, sharing stories of the challenging moments when Eun Mi endured domestic violence. A few days later, Eun Mi and Jin Hee learn about the discovery of a deceased girl's body in the news.
The possibility of Eun Mi being in danger worries Jin Hee. She decides not to reveal the full extent of the situation to Eun Mi. Instead, she suggests that Eun Mi stay at Jin Hong's place.
In a candid conversation with Eun Mi, Jin Hee finds herself unable to hold back and finally shares her bottled-up feelings about being Eun Mi's daughter, leading to a heated and emotional discussion.
Jin Hee plans a trip to reconcile with Eun Mi. Little does she know, Eun Mi, seemingly with no intention of making amends, invites an unexpected guest. And so, some sort of family trip begins.
Eun Mi and Ji Eun have fallen out and are not on good terms anymore. Their tension escalates when they run into each other at Jin Hong's residence. It doesn't take long before Jin Hee unexpectedly crosses paths with Ji Eun.
Jin Hong's parents, having become aware of Jin Hee's genuine status as their granddaughter and confirming it, wish to integrate into her life much like they did with their children.
