The team starts by Shin Cha IL interviewing the housing division director, Yoo Mi-Kyung, who had approved the project documents. Ms Yoo, who turns out to be Shin Cha-il’s college junior seems devastated over the embezzlement and blames the Union President, who proposed the business plan she approved due to unmet departmental targets. But then, she suddenly asks Cha IL how he is doing adding that she’s worried about him but Shin Cha IL reminds her that they are in the middle of an investigation.
Meanwhile, back at the office, Han soo and the others are speculating on the nature of the relationship between Ms Yoo and Shin Cha IL considering they used to be schoolmates and how she had cried hinting that they may have been a couple in the past but Seo Jin warns them to stop doing that in order to avoid rumors because Ms Yoo is already married.
Shin Cha-il who is skeptical of Ms Yoo enters and asks the team to audit her financial records making everyone shocked by how dismissive he is of school ties. Shin Cha-il, along with Han-soo and Seo-jin go to meet the victims to understand how they had invested their savings into the project. On their way out of the company, they run into a bitter vice president Hwang who tells Cha IL to give him condolence money since his salary has been reduced but Shin Cha IL chooses not to take him seriously and leaves with the other two.
Once the three arrive, Shin Cha-il checks the Union President’s house for clues. They meet a resident who recognises Seo jin. Turns out that Seo-jin and her mother used to live in the neighborhood, which is why she knows the people there. The resident tells them that the union president decieved them into signing the rennovation project. He even shows him a video of the president with a huge bag of money which he suspects is their money which he scammed them of. He also insists Ms Yoo was involved in the scam because she was the one who approved the whole thing.
Meanwhile, vice president Hwang gets wind of the Nanum project audit with a rumor circulating that Cha-il and Mi-kyung used to date. He discovers that the president is also not planning to spend generously at the funeral of the Housing Minister’s grandmother, which could impact their relations. He confronts him about this but the president refuses since he no longer wants to participate in acts of bribery and corruption. However vice president Hwang goes to see the minister himself and after offering his condolences, gives the Minister’s son an allowance, indirectly bribing the minister.
On their way back, Seo Jin points out that the union president may have also deceived Ms Yoo. However, Cha IL doesn’t spare her because even if that where the case, she was negligent in her duty. Although, she may not compensate for the money but she would face disciplinary action. Cha IL drops off Seo Jin and Han soo but they secretly follow him to a bar where they see him meeting up with Ms Yoo.
Ms Yoo seems concerned about Cha IL but he is cold, wanting only to interview her. He asks if she had met the union president in private but Ms Yoo denies it, saddened by his suspicion of her but Cha IL doesn’t bend and asks if she is having financial difficulty as he noticed that she is planning to transfer to the Florida branch. Ms Yoo later admits that she got a divorce and wants to escape, feeling ashamed that he’s witnessing such a hopeless side of her.
That night, as they are nearing Ms Yoo’s apartment, she points out to Cha IL that he has changed. He used to be warm and kind before but Cha IL ignores her and starts to leave only for Ms Yoo to fall out of drunkenness. Han Soo and Seo Jin who is still stalking them watches as Cha IL helps Ms Yoo into her house. Han Soo misunderstands thinking the two have a relationship but Seo Jin clears that Cha IL was just helping Ms Yoo. She wants to leave but Han Soo wants to remain spying to check if Cha IL will come out of Ms Yoo’s house. Seo Jin then leaves him behind.
At home, Seo jin tells her mother how their former residents were scammed of money due to the fake renovation hoping they would get new houses. Her mother feels grateful that Vice President Hwang, whom Seo-jin calls ‘uncle,’ brought them to a nicer place but Seo Jin is uncomfortable.
The next day, Han-soo remembers how he had drunkenly acted stupid in front of Shin Cha-il after Seo-jin had left, questioning him about his relationship with Ms Yoo. How he treated her gently unlike Mr Bae. He even taps Cha il’s butt and begs him to love him as well while hugging him.
When he arrives at the office, pictures of Shin Cha-il and Ms Yoo from last night has already been spread, and Shin Cha-il is accused of sexual assault because Ms Yoo had been admitted to the hospital claiming to be traumatized. Vice president Hwang happily accuses him. However, the president asks Cha il to sort out the mess rather than punishing him since Ms Yoo is under audit. Vice president Hwang is unhappy about this.
Meanwhile, Seo Jin asks Han soo if he remembers what happened last night but Han Soo claims to have been too drunk. Cha IL suddenly messages them both to meet him at the car park and asks if they saw anyone following them last night but they didn’t. He then tells them to do a proper job of stalking him next time.
In the car, Shin Cha EL announces they will be looking for the person who took the photos. Han Soo then apologizes for last night and asks him to clarify his relationship with Ms Yoo but Cha IL insists they only had a senior junior relationship.
Meanwhile, VP Hwang and the president have a tense meeting in the latter’s office as VP Hwang points out that he is trying to use Cha IL to get rid of him but if he wants to keep his position, he should just kill him.
Shin Cha-il, Han-soo, and Seo-jin then retrace their steps and meet Ms Yoo’s husband, who had taken the pictures. Cha IL asks if he planned the whole thing with Ms Yoo but the husband responds that his only goal is to keep Cha IL out of his wife’s workplace. He walks away and Cha IL tells the others that he is her ex husband. Seo Jin then secretly tells this to VP Hwang.
Meanwhile, VP Hwang strikes a construction deal with the deputy secretary and asks the president to give gifts to please him, but the president once again refuses, adhering to his principles.
Shin Cha-il confiscates Ms Yoo’s belongings in the office but he is restricted by her staff who accuses him of sexually assaulting Ms Yoo until VP Hwang arrives to quell the disturbance. But Cha IL ignores him and carries her belongings regardless. When Han-soo and Seo-jin confront Ms Yoo in the hospital, she says she’s hiding from her husband, who has been stalking her, threatening to kill her if she doesn’t do what he wants. She apologizes for the rumors promising to clear Cha il’s name. When they tell Cha-il, he believes she’s telling a lie.
In a flashback, it’s revealed that while returning from dropping Ms Yoo at her apartment, she had tried to seduce him but he gave her no chance. While leaving, he then overheard her husband calling her on the phone , angry that she had let Cha IL go so easily. They obviously wanted to set him up and failed.
Meanwhile, Seo Jin deduces to Han soo that it could be that Ms Yoo, her husband and the union president where all in cahoots to deceive everyone and that the president could probably have the money. Han Soo finds it shocking but Seo Jin tells him that as an auditor, he shouldn’t be shocked especially when people even kill each other over money. They part ways and that night, Han Soo tells his parents about his work.
The next morning, he suggests to Seo Jin that they should find the Union president but she is skeptical since even the police is unable to find him. However, Han Soo believes Cha IL will be able to find the president. Yeon gyeong seok tries to listen in on their conversation but they don’t let him.
Later, while searching through Ms Yoo’s social media account, Cha il finds a mountaineering club she’s part of. The union president is also part of the same club, and they go to meet the owner of the mountaineering club, who tells them the union president’s location after showing him pictures of the families that were affected due to the scam.
After asking around, Han Soo finds the president at a restaurant but he catches on to him and escapes. Han Soo chases after him and is unable to catch him as he flees in a bicycle but he is stunned when he sees Cha IL in a bicycle going after him. After a long chase, he catches him and turns him over to the police where his victims gather shouting and yelling at him.
The resident who had told them about his suspicion of the union president thanks Cha IL for finding the culprit but Cha IL is cold and doesn’t even say anything so Han Soo and Seo Jin answer for him assuring him that they will get their money back but unfortunately the union president exercises his right to remain silent and doesn’t reveal anything so Cha IL informs the resident that the investigation will take a long time which causes the man to nearly collapse. Han Soo and Seo Jin take him home and try to reassure him. They come across the residents two grand children on their way to feed the union president’s abandoned cat. However, they learn from the children that Ms Yoo’s husband came to the president’s house.
Meanwhile, Ms Yoo prepares to leave for Florida and is enjoying a farewell by her staff when Shin Cha-il suddenly asks to interviews her again surprising everyone. At the meeting with Seo Jin and Han soo present, he informs her about the union president’s arrest. He also reveals that her divorce is fake and that after fearing he would take the fall for everything, the union president claimed Ms Yoo suggested the embezzlement. However, when they both celebrated together, the money suddenly went missing. Cha il believes the money is with her husband Myung-chul since it was stolen from the union president’s house when he was with Ms Yoo. Seo-jin adds there’s a witness who had seen Myung-chul stealing the money. The witnesses are the old man’s grandchildren that Seo-jin and Han-soo are connected to. She is flustered but determined to travel but Cha IL tells her that her transfer is set to be canceled.
However, when Cha-il goes to report the case to the president, he finds that he has given VP Hwang authority over the audit department due to Hwang’s repeated pressures. Hwang orders the director to take her to the airport. When Shin Cha-il objects and orders Han-soo to stop her, Hwang fires him
