Branding in Seongsu

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. After hearing from Dong-beom, she suggested making big-size shoes for drag queens, and it was a huge success. 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.
