Despite Na-eon's continued success in securing significant marketing deals, she finds herself bothered by an intern named Eun-ho. Despite being just an intern, Eun-ho consistently disrupts Na-eon's routine. Frustrated, Na-eon decides to confront Eun-ho in an eerie location, possibly indicating that she has reached her limit.

Eun-ho vehemently opposes animal cruelty, and it was this very conviction that led him to take a stand against his own company when he was just an intern during a recent incident. To quell his curiosity, Na-eon puts an end to his suspicions by arranging a meeting with XU Beauty. Content for the moment, Eun-ho quickly moves on to visit one of XU Beauty's factories, unaware of the surprises that await him later in the day.

Eun-ho, oblivious to the gravity of the information he stumbled upon, feels compelled to share his discovery with Na-eon. However, her reaction is unexpectedly calm, contrasting with his anticipation. Despite the unsettling nature of what he witnessed at the factory, the collaboration between XU Beauty and Seongsu Agency proceeds seamlessly, leaving Eun-ho bewildered by the apparent ease with which the project advances.

The Na-eon's XU Beauty event unfolds seamlessly, garnering a positive response from the public. Yet, what appeared to be another flawless project marks the onset of Na-eon's significant downfall. The morning after, she encounters an entirely new disaster, and the solution she believed would pave her way out unexpectedly places her in grave danger.

Na-eon wakes up in the hospital, trapped in Eun-ho’s body. To figure out exactly what happened, she continues living Eun-ho’s life and realizes that at Seongsu Agency, he has been assigned to Team Underdog, a team full of troublesome employees that is led by none other than Yoo-mi.

Na-eon, who is in Eun-ho’s body, starts to organize Team Underdog to get to work. However, her efforts are stifled by Yoo-mi’s plans to keep Eun-ho in check, which deepens the war of nerves between Na-eon and Yoo-mi. Meanwhile, Na-eon thinks about how a soul swap between her and Eun-ho could have occurred.

Being trapped in Eun-ho's body, Na-eon is trying hard to track down the person who tried to kill her.

Meanwhile, Na-eon receives a call from the hospital, and she sees the guy with the rabbit mask there.

In a TV interview, Yoo-mi claims that Na-eon simply took a fail and she didn't commit suicide because of the company. Meanwhile, Na-eon wakes up from a coma. In order to switch the soul back, Eun-ho suggests kissing each other.

Feeling frustrated, she goes to meet someone who has been behind her, and Eun-ho follows her. Meanwhile, Yoo-mi tells Eun-ho about an upcoming project.

Eun-ho accepts the new project, and while doing so, Team Underdog also gets a chance to compete. Na-eon and her team go out for market research, and they run into Jenny. Meanwhile, Eun-ho asks Yoo-mi to make an appointment with Nam Yoon-hyuk.

Both Yoo-mi and Na-eon are working hard on the rebranding project. Inspired by Jenny, Na-eon comes up with an innovative idea. Meanwhile, Yoo-mi has a secret weapon for her project, and that is Yoon Nam-hyuk, the sexy symbol of this generation.

Seongsu Agency and Segye Group are in the headlines of a scandalous situation because of Yoon-hyuk, the soju model of Yoo-mi's rebranding project. Yoo-mi is done for, and Na-eon's non-alcoholic drink concept has become a huge success.

Eun-ho gets a mysterious message and he goes to the restaurant that is mentioned in the text. He sees Director Han there. All of a sudden, both Eun-ho and Na-eon have a serious headache, and their souls get switched back. Meanwhile, Na-eon finds out that Director Han is the guy behind Yoo-mi.

Five years ago, Na-eon and Eun-ho bumped into each other accidentally at Segye Group, and their materials for branding presentations got mixed up. Just like that, Da-eun's ideas of Bandi Candles were in Na-eon's hands and Na-eon turned Da-eun's ideas into hers.

Yoo-mi overhears the conversation between Na-eon and Eun-ho. She finds out the secret that they went through a soul switch and wants to use this secret to bring down Na-eon. Meanwhile, Na-eon wants to find out what evidence Director Han has in his hands. In order to do that, she will have to secure the deal with HQ Motors.
