First Impression

Kim Sa Ra is a talented lawyer and works for the top law firm in South Korea, Chayul, where her mother-in-law, Hui Won, is the chairwoman and her husband, Yul Seong, is the CEO. Unfortunately, her mother-in-law doesn’t appreciate Sa Ra and doesn’t treat her like a member of the family. Today is the birthday of her mother-in-law, and Sara arranges a big party for her, but Hui Won asked the staff to allow only her son and grandson to be with her at the first table. She doesn’t even let Sara call her "mom" but insists on being called "the chairman" even when they are at home. Sara notices this and is quite upset, but she still tells the staff to add her name to the table because she thinks if she tries hard, with time, Hui Won will accept her. But little does she know, her husband, Yul Seong, is cheating on her while being such a muppet to his mom. At the party, Sara sees her name is removed from the family table again, and Hui Won doesn’t even introduce her to their guests. After the party, Sara feels sad and visits her mom at her noodle shop. It turns out that all of that bad treatment from her in-law is just because Sara comes from a humble background, and her mother-in-law looks down on her. Her mom doesn’t know what Sara has to endure at home and is happy and proud of her daughter. Sara’s dad died in an accident at a construction site, and it was very difficult for them back then. Sara's mom says that as long as she is happy, she will also be happy. Sara returns home and inquires about her mother-in-law, but she insults her, saying that the smell from her maternal home is very bad and that she needs to call her "Chairman" instead of "mom." Sara tries to talk with her husband about that, but he doesn't care and tells her to just suck it up. The only joy Sara has at home is her little son. One day, Chayul Law Firm receives a divorce case of a defendant accused of domestic violence, hospital Director Kim. He is an important customer because if Chayul can win his cases, all the cases related to his hospital will be assigned to Chayul. Sara realizes that this case is very difficult to resolve because he is famous for being violent, and the court will likely favor his wife. Seeing Sara reluctant to take the case, Hui Won offers a condition that if Sara wins, they will promote her to corporate director, and she will allow Sara to call her "mom." Sara used false evidence to prove that Director Kim was also assaulted by his wife to help him win custody of their child. However, the wife’s lawyer has video evidence of Director Kim and Hui Won in an elevator and uses it to prove his affair, sa ra rejects the accusation but this is their plan to stir up public opinion to defame Mr. Kim's hospital and the Chayul Law Firm. Meanwhile, Prosecutor Gi Jun and his associate are investigating an illegal drug distribution case to a gay bar and discover a connection to Director Kim. Gi Jun goes to Mr. Kim’s hospital and confiscates his documents for the investigation. When Sara hears the news and goes there, she meets Gi Jun. They used to be in love but now act like strangers. Although Gi Jun appears indifferent, he is actually curious about Sara’s recent life and asks a colleague to inquire about her. Afterward, Sara is informed by her assistant that the investigation has discovered that Mr. Kim is gay and has also distributed drugs to a gay bar. Just then, Sara also realizes that the position of corporate director has been given to Lawyer Ma, a detestable person in the firm. Sara, angry, confronts Hui Won to ask her why she went back on her word. Hui Won does not answer and asks Sara what she plans to do about it. Sara says that if that's the case, she will act according to her conscience. At the next trial of Director Kim and his wife Son Jang Mi, Sa Ra goes to the restroom and speaks loudly so Jang Mi can hear that if they show evidence of Mr. Kim's interest in men, Jang Mi will win the case and get custody of her son. Jang Mi and her lawyer do that, and she wins the case. Meanwhile, Hui Won tells Yul Seong he must leave Sa Ra and find a way to marry the daughter of the Judicial Council chairman to change the law, open their school, and start the Yul Town project. It turns out Hui Won secretly uses Sa Ra's documents to divorce her from her son. Moreover, she uses Sa Ra's documents for a fake marriage with a foreigner, with the reason to get her grandson into an international school. The prosecutor's office investigates this, and Hui Won does this purposely to trap Sa Ra, send her to prison so Yul Seong can marry the chairman's daughter and improve the Chayul law firm's position. Yul Seong goes to the prison to tell Sa Ra about the divorce and that he will take care of their child, and he will support her after she gets out. However, Sa Ra already figure their plan of sending her to prison so he can remarry and vows to get back custody of her child when she gets out. However, Kang Bom, Sara's old assistant, announces that Hui Won has perfectly forged the documents give up Sara's parental rights, and she also can't secure custody of her child. Kang Bom feels sorry for Sa Ra, but Sara tells him she won't give up. The day of Yul Seong and his new fiancee Han Ji In's engagement party arrives, and Yul Seong's ex-lover shows up at the party and causes a scene. Gin Jun also learns from a friend about Yul Seong quickly divorcing Sara as soon as she went to prison and marrying the prosecutor's daughter to advance his career. A few days later, the media report on a young woman named Na Yoo Mi found dead on the road. The investigative authorities suspect it was just a traffic accident, but her grandfather does not believe it and protests to demand justice for his granddaughter. Gin Jun is in charge of this case and realizes that Yul Seong was the last person to meet Na Yoo Mi before her death. Therefore, he summons Yul Seong to the prosecutor's office for questioning as part of the investigation. At Sara's mother's noodle shop, a part-time employee realizes that she had seen the victim at an event she worked at the previous night. At that time, the young woman had dropped her phone into a flower basket, and thanks to that, a video was recorded of Yul Seong meeting Yoo Mi and later instructing his men to eliminate Yoo Mi. In the prison, Sara realizes that she has to be stronger and starts to practice fighting in the prison gym room. She is then surprised when Jang Mi visits her. Unlike Sara, Jang Mi's life has turned a new page after the divorce. Sara is curious about Jang Mi's reason for the visit. It turns out Jang Mi wants to collaborate with Sara to start a divorce support service for the people in need. Sara refuses because she is in prison and won't be able to practice law for the next five years, but Jang Mi still asks her to contact if she changes her mind. Meanwhile, Sara's mother calls Gin Jun to inform him about the evidence regarding Yoo Mi's murder. He asks her to meet at the prosecutor's office. However, while she is waiting for Gin Jun, Yul Seong is also there and spots her from afar. He sends someone to lead her away, lying that they are going to meet prosecutor Gin Jun. When Gin Jun reaches the reception, she has been taken away. He checks the security cameras but still can't understand what really happened. Soon, Sara is allowed to go home, but tragically, it's to attend her mother's funeral. They find her mom dead at her dad's old work site and assume she decided to take her own life. Sara is shocked when she receives this news and becomes even more furious when she sees Yul Seong at the funeral. After the funeral, Yul Seong meets with his secret society. They introduce a new member, Professor Seo, who also was the last person to talk to Yoo Mi before she dies. Gi Jun calls him for an investigation after he refuses to cooperate and hand over his phone multiple times. The last time Gi Jun calls, Professor Seo jumps out of the window trying to kill himself but luckily survives and falls into a coma. This leads to a wave of protests against prosecutor Gi Jun's forceful investigation tactics. Gi Jun's boss, who is close to Yul Seong, scolds him for this. However, Gi Jun feels it's unfair and declares his resignation to the press. After some time, Sa Ra finally gets released from prison, now much stronger both physically and mentally. Jang Mi picks her up from prison. Touched by Jang Mi's kindness and sincerity, Sa Ra agrees to her proposal to work together. Sara also says she wants to take revenge on Yul Seong and put him in prison for what he did, so she can win custody of her son. They quickly start a support service called Solution and also recruit more staff, including Kang Bom and a man named Dae Ki. The first client is a famous writer named Lee Joo Won who is married to news presenter Jang Jae Kook. They are known online as a powerful couple. However, Jang Jae Kook gets involved in a harassment scandal with a female colleague and quickly faces boycotts from the broadcaster and the audience. Lee Joo Won wants to divorce him to protect her and her daughter Soo Ji's reputation, who has to endure public scrutiny and bullying at school. While they are talking, Soo Ji calls Joo Won to say goodbye. Feeling something is terribly wrong, the Solution team takes Joo Won to the school and finds Soo Ji standing on the rooftop, ready to jump. The Solution team finds a way to get to the rooftop. Sara gets on the balcony and tells Soo Ji about how her own mother had jumped from a rooftop and tells the girl to think about her mother. Soo Ji is then convinced and is about to go down but she slips and falls, but Sara manages to catch her. They save Soo Ji and she is sent to the hospital with her mom. The Solution team comes back to their office and Sara is convinced to help Soo Won. Funnily enough, Jae Kook's litigation lawyer is from Chayul Law Firm. The strange thing is that although Soo believes her husband harassed the colleague and wants a divorce, she still posts pictures of messages between the two proving that it was consensual. Sara continues to search for her son but still hasn't heard any news. Jang Mi meets her and presents a file of someone who applied to be a legal advisor for Solution. To Sara's surprise, it's no one else but Gi Jun. Jang Mi is excited to hire a former prosecutor to work for them, but Sara is not very comfortable with this idea. The next day, Sara has to meet Gi Jun for a job interview, and the meeting is very awkward. Sara tries to talk about work, but Gi Jun keeps bringing up their history from nine years ago. It turns out that nine years ago, the night before Sara's wedding, they planned to run away together, but Gi Jun didn’t show up, and Sara ran to his house in the rain. There, Gi Jun told her that he had changed his mind and wanted her to marry Yul Seong. However, when Sara was about to leave, he hugged her and asked her to stay, but this time Sara chose to leave. In the present, Sara tells Gi Jun to decline the job offer from director Jang Mi, however, Gi Jun doesn’t want to miss the opportunity to work with Sara and insists on working for Solution, promising that their past relationship will not affect their work.
