At the meeting to select the next president of World Department Store, Sylvia Choi throws the meeting into chaos by revealing a photo of Nabi and Woojae together, saying that an immoral person who has an affair with a married woman cannot be appointed as president. Meanwhile, Nabi is disappointed to find out that all of her orders are fake, but she does not give up and as she is thinking about coming up with a solution, she remembers what Seola told her...

Woojae confirms Nabi's feelings for Jeongwook, saying that he decided it would be better to confirm it rather than keep it in Nabi's heart. Nabi harshly tells Woojae that she is still in love with Jeongwook and that she should break up with him, and she takes a taxi alone and leaves...

Meanwhile, Seola is devastated when she realizes that the envelope she ran away with from the scene of the accident was Nabi and Jeongwook's divorce papers...

Soojeong is surprised to see that the bracelet she brought, saying that Nabi was found at the scene of the accident, is the bracelet she gave Seola as a gift.

Meanwhile, Woojae hears from Baekgi that the car Shinja and Jeongwook were riding in was Sylvia's car and goes to see Chairman Lee...

She calls Chairman Lee and threatens him that if he does not help her, she will tell Woojae and the media that Chairman Lee was following Woojae's mother. Meanwhile, Nabi learns the secret of the yellow envelope that Seola is looking for when she sees that Herian Shu's name is Soojeong's name, not Sylvia's name...

Meanwhile, Seola provokes Moon Hyeongshik by saying that she cannot give him money because of Jeongwook. Hyeongshik visits the hospital where Jeongwook is hospitalized, asking Seola to give him money so he can get rid of Jeongwook...

Nabi tells Seola that since she found the envelope, don't think about running away, but cooperate in catching Hyeongshik and turn yourself in. Meanwhile, Seola suggests taking over Herian Shu, citing rumors of Jiyeon's scandal...

When Seola sees Hyeong-shik, who injured her head in an argument, she runs away to the charnel house where Sanghyeon is in fear out of fear and sends her seal by courier along with a note saying she is sorry to Soojeong. Meanwhile, Nabi receives a call from Seola apologizing for what she has been doing, and out of anxiety, Nabi goes to the villa with the number on it...
