Sara thinks she needs to make Yul Seong uneasy, so she pretends to kiss Gi Jun and tells him she wants to find out why he is scrutinizing her and Gi Jun like that. Sara still believes that Gi Jun is using her to investigate Yul Seong, despite his explanations. She reminds him of his three-month promise when starting the job and hints that he should leave.

Sara returns home and finds Yul Seong already there, continuing to tell her to fire Gi Jun because he is taking advantage of her. Sara says it is not his business and sends him away.

The next day, Kang Bom informs Sara about the likelihood of Yul Seong's bill and his group's passing.

She then meets with Representative Kim Young Ah of the Han Joo party to prevent Yul Seong from gaining more power. Young Ah immediately recognizes Sara as Yul Seong's ex-wife and asks for her help with her marriage. It turns out her husband is demanding a divorce; they have two children, but both are her husband's from another relationship. However, Young Ah dearly loves them and wants custody rights, so she is adamant about not wanting a divorce.

The solution is found upon learning that Young Ah's husband, Min Chul, CEO of a company about to go public, seems in a hurry to divorce now because if the divorce happens after the listing, the assets to be divided would increase significantly.

The solution team later arranges a meeting with the husband to mediate. They discover the reason he is adamant about divorcing his wife is that he followed the prophecy of a pastor. This pastor had declared that Young Ah and her work were incompatible with her husband's business activities. Sara suggests that Young Ah would agree to a divorce if Min Chul would grant her custody of the children. However, he states that if Young Ah does not agree, he will proceed with a unilateral divorce. They feel this time they have two adversaries: the husband and the pastor who has manipulated him through superstition.

Yul Seong meets with Young Ah to convince her to support his bill, but Young Ah bluntly refuses to cooperate with those who are disloyal to their partners.

Meanwhile, the solution team investigates the pastor and his sanctuary, who is famous for being able to predict the future and cure all kinds of diseases. He is also the person who advised Min Chul to buy stocks, leading to a significant profit, which is why Min Chul highly trusts the pastor.

Gi Jun finds Sara in the office, and they both feel awkward after what happened the day before. Dae Ki suggests the entire office go out to eat, and Gi Jun shows off his ability to perform magic tricks by moving objects, placing a ring on Sara’s finger.

From this, everyone starts to suspect that the pastor also uses tricks and that his healing might largely depend on the placebo effect. Gi Jun invites Sara to his house to talk, showing her a diagram with the information they've gathered about the Yoo Mi case and Professor Seo. Yoo Mi has died after falling from a moving taxi, a case the police suspect to be a suicide. However, a woman calls to report the death, claiming it wasn't a suicide. Unbeknownst to both of them, the woman who made the call is Sara's deceased mother.

Both cases are very murky, which is why Gi Jun feels compelled to investigate further.

The next day, Secretary Jang meets with Yul Seong to report on Sara and Gi Jun. She also mentions that Young Ah has come to Solution asking for their help to prevent her divorce.

Hearing this, Yul Seong becomes intrigued and abruptly leaves Jang to investigate further.

Upon arriving at the Solution office, Sara greets her and apologizes for the tension between them the previous day, emphasizing that they are a team. This gesture somewhat moves Jang.

Meanwhile, Yul Seong, unable to persuade Young Ah, approaches the pastor and asks for his help to discredit Young Ah.

They arrange a fake conversation where the pastor claims he has been a crucial advisor to Young Ah in her election campaigns, and that she frequently sought his counsel. This conversation is recorded by a security camera at a restaurant and then leaked online. The next day, even Min Chul is shocked by the pastor's blatant lies, but the pastor claims that the villains have forged the conversation, and the naive husband immediately believes it. The night before, it turns out, Yul Seong had convinced the pastor to lie because, even if Young Ah refutes, he would have created rumors to polish his own name.

This news quickly causes Young Ah trouble with other representatives, so the Solution team believes they need to find a way for Min Chul to come forward and explain.

Having no other choice, Gi Jun and Director Jang Mi disguise themselves as fanatics to join the pastor's congregation. Director Jang Mi disguises herself as a blind person, and Gi Jun as her brother, asking the pastor for blessings and a cure. All their images are secretly filmed and streamed live to the Solution team waiting outside.

After a while, the pastor brings in a cancer patient and allegedly removes a tumor from the person with his hands.

However, when they sneak in, they discover the tumor is fake, hidden under the patient's bed for the pastor to perform his deceitful act.

Upon exiting, they also encounter a man causing a commotion in the lobby, accusing the pastor of urging his wife to divorce him.

As they are trying to leave, a church enforcer guesses that Gi Jun and Jang Mi are spying on them and calls for their capture. Gi Jun fights back, and they successfully escape with the Solution team. The following day, Sara and Gi Jun bring the video to Min Chul, but he still trusts the pastor and thinks it's a trick by the Solution team fabricated to prevent him from divorcing his wife. Sara also threatens to release the video online and let everyone know about Min Chul's close relationship with the pastor, which could affect his business. Min Chul meets with the pastor and asks him to clarify the rumors, explaining that if his business suffers, he won't be able to donate to the pastor's church. The pastor then calls Yul Seong, pretending that all the images and sounds in the video uploaded to slander Young Ah were fake and created by Yul Seong's people, and he will sue them. he cut ties and asserting he has nothing to do with Yul Seong. Meanwhile, Gi Jun meets with Professor Seo's wife, who reveals that she has discovered Professor Seo transferred one billion to a company of a five-person association. She also recovers her husband's phone and gives it to Gi Jun for investigation, but all data had been wiped by Yul Seong's people.

Gi Jun brings it back to Solution, and Dae Ki quickly restores the phone's data. They discover the last call Professor Seo made was to Yul Seong just before he jumped out of the window. He messaged Yul Seong asking for his one billion investment back, but they refused and continued to insult him. They also sent him a secret video, threatening to send it to his wife and daughter if he revealed their secret to the police. Cornered, Professor Seo jumped from the staircase.

They compile all the data and evidence onto a USB along with Professor Seo's phone and give it to Jin Woo, a prosecutor and friend of Gi Jun, hoping he will bring Yul Seong to justice. However, Jin Woo has been threatened by Yul Seong's people for gambling and destroys all the evidence.

Gi Jun returns home to find it ransacked. Worried, he calls Sara but gets no answer. He drives to her house, finds the door unlocked, and as he enters, someone knocks him down from behind.

At that moment, Sara returns to the hallway to see a masked person running away. When she enters her house, she finds the door unlocked. Opening the door, she finds Gi Jun unconscious on the floor with blood coming from his head, and her house has been ransacked.
