After Bit Chae Woon meets a woman who could be her biological mother, she feels sorry for Sun Jeong. Sun Jeong thinks the woman who had approached her is strange, which leaves her feeling unsettled. Meanwhile, Bit Chae Woon's siblings discover she is looking for her biological mother, which starts a huge argument among them.

Out of anger and frustration, Chae Woon heads to the CEO of LX Fashion's house. At the gate, she faints, and Jung Won takes her in. Jung Won promises Chae Woon that she'll look into the case. Later, Jung Won calls Chae Woon into the office to explain the evaluation process. Even after hearing the explanation, Chae Woon still wants to prove her innocence, so Jung Won offers her an internship instead of giving her the prize.

Chae Woon loses her patience and lets all her frustration out on Sun Jeong. Hae Deun, Ra Hoon, and Man Jeong stick up for Sun Jeong, but they each get a taste of the painful stories she had been keeping inside. Man Jeong, who gets the worst of it, goes out drinking solo and returns on Hwak Se's back. The next day, Chae Woon realizes she's lost her cell phone.

After reuniting with Jung Won, Sun Jeong, without knowing, feels immensely guilty about her happiness to see her. Jae Hee is thrown into a storm of confusion when he learns about Chae Woon's past, and Min Jae shouts a startling remark at Jung Hoo, who had been secretly tailing her. Meanwhile, Chae Woon confronts Seo A when she sees she was deliberately excluded from the interns' presentation.

Jung Won receives a mysterious call regarding her lost daughter. She's shaken over it. Hae Deun causes trouble again, and this time, she used Man Jeong's credit card without permission.

Later, Jae Hee tries to talk some sense into his dad, but instead, he ends up renouncing his inheritance. Meanwhile, Chae Woon visits So Mi and Hae Deun auditions for Slight Entertainment.

Jung Hoo gets on his knees and begs Min Jae to come back home, but Min Jae doesn't falter in her determination to get a divorce. Jae Hee overhears Hae Deun and Ra Hoon talking and finds out that Hae Deun didn't pass the audition. Jung Won and Sun Jeong meet up for dinner and catch up with each other. Jung Won is happy to reminisce about the good old days with Sun Jeong, but Sun Jeong isn't so comfortable with her. Min Jae and Jung Hoo end up getting divorced, leaving Jae Hee heartbroken.
