Meanwhile, Na-bi mistakes Byung-ho, who came to her house, as her investor...

Na-bi, who knew Jung-wook as an orphan, did not trust Jung-wook's family whom she met in Mejikong, so she showed him a photo of Jung-wook when he was young. Na-bi, confused about her husband's identity, eventually starts investigating Jung-wook, and when Seol-ah finds out, she trembles with anxiety.

Jung-ae tells Na-bi to quit her job, but Na-bi does not give in to her wishes. Meanwhile, Baek-gi becomes jealous when Chan-ki helps Gook-hee with her studies and it seems like this will bring them closer...

Gook-hee and Shin-ja are worried about Na-bi not returning home, and they lie to Jung-ae that Na-bi has already come home and is sleeping. Seol-ah is also angry when Mo-ran says that Woo-jae did not come home. When PD Yoon asks her what her relationship is with the head of the World Department Store, who has promised to support production costs on the condition of Na-bi's appearance, Na-bi becomes curious about the existence of the manager and goes to meet him.

To make matters worse, Na-bi is sued by Ji-yeon for assault, and when filming for the drama is halted, the production company demands compensation from Na-bi for damages. Woo-jae, who was running around in every possible way to help Na-bi who was taken in by the police and interrogated, realizes that his own strength is not enough and asks Chairman Lee to help him.

Meanwhile, Woo-jae tries to call Na-bi, but she doesn't answer, so he becomes anxious...

Na-bi faces an emergency, and Woo-jae becomes suspicious of Seol-ah and interrogates her. In the intensive care unit, medical staff continue to perform CPR on Na-bi, but her heart monitor does not budge. When this news is delivered to her family, the house becomes filled with tears...

Na-bi is discharged safely. Her family all welcomes her by setting off firecrackers, cheering and clapping. Jung-wook calls Jung-ae and tells her that he will return to Na-bi. Meanwhile, Na-bi that passes by Woo-jae's hand brings back memories of her going to the beach together...

Shin-ja asks Woo-jae to keep Jung-wook's affair a secret from Na-bi. Na-bi runs to Jung-wook and hugs him out of joy, and Woo-jae stops when he sees her. Meanwhile, Yoo-jin can't stand her anxiety and calls Jung-wook...

Yoo-jin yells at Jung-wook that she can't stand it any longer and tells him to get out of the house where Na-bi is. Na-bi, who happened to witness this situation, has a cold expression on her face. While eating together, Na-bi asks Jung-wook and Yoo-jin if they are simply boss and co-worker...

Na-bi leaves the store angrily, saying that Jung-wook will definitely be punished. Embarrassed, Yoo-jin follows Na-bi and accuses her of having different promises, but Na-bi perseveres and heads to the police station. Yoo-jin calls Junior Nam-goong and asks for help to stop Na-bi...

Jung-wook hurries out, saying he will go home to Seoul to pick up evidence that will prove his innocence. The detectives follow behind them, and Na-bi and Woo-jae also go up to Seoul. Meanwhile, Yoo-jin gets angry at Jung-wook's words that she will not come back to him and slaps him...

Woo-jae yells at Chairman Lee, asking what kind of deal he had with Seol-ah, and Na-bi overhears his answer and is shocked. Woo-jae tries to reassure Na-bi that he will take care of things, but Na-bi says she can't just sit back and watch. Meanwhile, Yoo-jin vows that she will put Seol-ah in prison no matter what she does...

Seol-ah asks Chairman Lee to return all the evidence since she doesn't have to give him the money, but Chairman Lee refuses. Chairman Lee is displeased with Seol-ah for not trusting him and gets angry and tells her not to bring up the story again. Meanwhile, Woo-jae goes to find Na-bi...

The family becomes worried when there is no contact from Jung-wook after his release, and they decide to visit him at home in Seoul. Meanwhile, while Seol-ah is being investigated by a detective, she calls Chairman Lee and asks him to protect her, but Chairman Lee hangs up the phone and tells her to pay for her crime...

The family sets up a memorial service at the Butterfly Shoe Store and prays for success. Chairman Lee learns that the people who bought Seol-ah's stocks were Jung-wook and Yoo-jin, and orders him to find out more. Meanwhile, Woo-jae goes to Sung-ryong to report on a project commemorating the founding of the department store...

Woo-jae announces the mission task for the first round of the store entry competition finals. Na-bi is embarrassed by the difficult task, and Seol-ah raises a question. Startled, Na-bi runs after Seol-ah and asks how she got out of prison so quickly. Seol-ah says something meaningful and then storms off...

At the meeting to select the next president of World Department Store, Sylvia Choi throws the meeting into chaos by revealing a photo of Na-bi and Woo-jae together, saying that an immoral person who has an affair with a married woman cannot be appointed as president. Meanwhile, Na-bi 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 Seol-ah told her...

Woo-jae confirms Na-bi's feelings for Jung-wook, saying that he decided it would be better to confirm it rather than keep it in Na-bi's heart. Na-bi harshly tells Woo-jae that she is still in love with Jung-wook and that she should break up with him, and she takes a taxi alone and leaves...

Seol-ah visits Jung-wook and asks him about Chul-hee, whom Sylvia is looking for. When Jung-wook hears through Seol-ah that Sylvia went to see Sung-ryong, he becomes anxious that she might notice her son's presence. Meanwhile, while Baek-gi is trying to secretly give Soo-jung's nutritional supplement to Gook-hee, he is caught by Chan-ki and gets into a fight with him. Afterwards, he learns that Soo-jung's nutritional supplement is an anti-cancer drug.

Na-bi chases after Sylvia to persuade her to leave the store, finds Sylvia sitting down because she can't see, and takes her to the hospital. When Sylvia, who cannot see her eyes, calls out for her Chul-hee, Na-bi wonders if Sylvia is Woo-jae's mother...

When Sylvia sees the photo of the lost Na-bi at Seol-ah's store, she vows to get revenge on Seol-ah, saying that Jung-wook and Seol-ah tricked her and played with her even after finding out that Woo-jae was her son. Meanwhile, Chairman Lee asks Sylvia, who came to visit Woo-jae as her mother, to go abroad and leave Woo-jae's side...

Sylvia asks Jung-wook to hide the fact that she knows Woo-jae from Seol-ah until she finds the money Seol-ah hid. Meanwhile, Jung-wook sees Na-bi waiting for Woo-jae, shivering from the cold morning air, and says he will divorce her...

The Mejikong family and Na-bi rushed to the hospital as soon as they heard that Shin-ja and Jung-wook had been in a car accident and were admitted to the hospital, but due to the long delay, they were saddened when the doctor told them that they could die during the surgery. Meanwhile, Seol-ah is devastated when she realizes that the envelope she ran away with from the scene of the accident was Na-bi and Jung-wook's divorce papers...

Soo-jung is surprised to see that the bracelet she brought, saying that Na-bi was found at the scene of the accident, is the bracelet she gave Seol-ah as a gift. She goes to Seol-ah and asks where the bracelet she gave her as a gift is and asks about the accident scene. Meanwhile, Woo-jae hears from Baek-gi that the car Shin-ja and Jung-wook were riding in was Sylvia's car and goes to see Chairman Lee...

Seol-ah watches the video captured in the black box and sees a car that was following Jung-wook's car. She calls Chairman Lee and threatens him that if he does not help her, she will tell Woo-jae and the media that Chairman Lee was following Woo-jae's mother. Meanwhile, Na-bi learns the secret of the yellow envelope that Seol-ah is looking for when she sees that Herian Shu's name is Soo-jung's name, not Sylvia's name...

Woo-jae tells Na-bi to sue Seol-ah one more time to retrieve the money she hid, and this time suggests doing it in Gook-hee's name. Meanwhile, Seol-ah provokes Hyung-shik by saying that she cannot give him money because of Jungwook. Hyung-shik visits the hospital where Jung-wook is hospitalized, asking Seol-ah to give him money so he can get rid of Jung-wook...

Na-bi tells Seol-ah that since she found the envelope, don't think about running away, but cooperate in catching Hyung-shik and turn yourself in. Meanwhile, Seol-ah suggests taking over Herian Shu, citing rumors of Ji-yeon's scandal...

When Seol-ah sees Hyung-shik, who injured her head in an argument, she runs away to the charnel house where Sang-hyun is in fear out of fear and sends her seal by courier along with a note saying she is sorry to Soo-jung. Meanwhile, Na-bi receives a call from Seol-ah apologizing for what she has been doing, and out of anxiety, Na-bi goes to the villa with the number on it...
