The hotshot professor at Korea’s number one university is even on his way to the presidency. Geun Woo plays the perfect husband in front of his family but is actually being unfaithful to his wife Hye Ryul. Meanwhile, Hye Ryul goes up against Jusung although it is run by her in-laws. This case goes viral and grabbed the whole nation’s attention.

The Christmas Fund that many people talk about is suspected as the cause of a person’s death. Certain that it is a murder case, Gu Won digs deeper despite the danger. Hye Ryul gains enough power to compete with her husband for the presidency. Nobody is able to figure out what the competent couple has in mind

Gwang Jeon finds out about Geun Woo’s affair, but does not use it against him yet. However, she is not the only one who knows about it. Meanwhile, crucial information regarding Hye Ryul’s investigation gets leaked to the press. Although it causes some difficulties, it does not stop her from doing what she thinks is right

Nan Hee asks Hye Ryul to buy her a drink after she helps her with the computer. As Geun Woo also tags along, the air becomes tense. Meanwhile, Hye Ryul decides to help the police with their investigation on the Christmas Fund. Just before their great arrest, something goes sideways and their only chance disappears.

After watching Ji Joon Ki’s interrogation, Hye Ryul asks Geun Woo out to dinner. At the couple’s favourite restaurant, Hye Ryul tries to comfort her husband by showing how much she appreciates him putting up with her mother. Just then, Kang Baek shows up with his friends and suggests that they join Hye Ryul and Geun Woo. Geun Woo’s face stiffens.

To sabotage Nan Hee’s plan, Hye Ryul asks Kang Baek to bring Ji Yi home for dinner to discuss their marriage. The whole family gathers and prepares a feast to welcome their future family member, Ji Yi, only to be surprised by who turns up at the door. When Ji Yi finds out about the dinner, she asks her dad to stop the investigation on Jusung.

News reports on Chairman Ji’s letter and his claims give Hye Ryul and everyone involved in this case a headache. But what torments Hye Ryul the most is what Nan Hee tries to do with her son. When Hye Ryul gets a text from Kang Baek that he might not come home, she starts to fret frantically. Meanwhile, Geun Woo meets with Nan Hee to try and stop her from using Kang Baek for her revenge.

At the mock trial competition, the students argue over a case that’s made up based on the actual case from 20 years ago. During the trial, Nan Hee becomes overly zealous, which piques Gun Do’s interest. Meanwhile, Hye Ryul and Geun Woo’s kiss in the car made the headlines, successfully diverting the public’s attention from the investigation.
