Na Eon, a ruthless marketing ace, clashes with righteous intern Eun Ho while chasing a brand deal with XU Beauty. He suspects animal testing, and their tension spark rumors about a love-hate romance.
Na Eon sends Eun Ho to inspect the site to ease his suspicions, though she’s also uneasy about XU’s past controversies. There, Eun Ho accidentally stumbles upon XU Beauty’s hidden animal testing lab.
Eun Ho shows Na Eon the evidence, but she warns him to stay quiet. She exploits it to raise contract fees and bribe cobblers, ensuring the success of their pop-up project.
Appalled by Na Eon's methods, Eun Ho declares war and reveals his backup footage. When XU's scandal goes public, Na Eon is fired as the scapegoat and later attacked by a masked figure.
Na Eon wakes in Eun Ho’s body, while her own lies unconscious in the ICU. Returning to the agency, she’s made full-time but sent to the misfit “Team Underdog.” Her hunt for the culprit begins.
Team Underdog is mocked for their presentation as Yu Mi hands them Na Eon's leftover project. When Na Eon visits her body in the hospital, she recalls her kiss with Eun Ho, suspecting it might switch them back.
