## Spoilers

### Premise

Kang Na-eon is the youngest marketing team leader at the Seongsu Agency. Starting out as a recruiter, she climbed the corporate ladder through relentless work and deep personal sacrifices, completing every project she took on and becoming something of a legend in the industry.<sup>[4](https://tv.apple.com/kr/show/branding-in-seongsu/umc.cmc.2jswgbkfnz8wquzf0b66zv8r7?l=en)</sup> So Eun-ho, who spent most of his life with a "YOLO" mindset, surprises everyone by joining the workforce as an intern at the same agency, where his carefree attitude and youthful appearance make him the oldest intern but not a universally popular one.<sup>[4](https://tv.apple.com/kr/show/branding-in-seongsu/umc.cmc.2jswgbkfnz8wquzf0b66zv8r7?l=en)</sup>

The two hold opposing values and dislike each other from the start. After an unexpected kiss, their souls swap bodies, forcing each to live in the other's position; the series follows whether learning to walk in each other's shoes is also the key to switching back.<sup>[4](https://tv.apple.com/kr/show/branding-in-seongsu/umc.cmc.2jswgbkfnz8wquzf0b66zv8r7?l=en)</sup> In AsianWiki's synopsis, Na-eon lands an exclusive marketing contract with XU Cosmetics that could raise her to an executive position at the agency's parent company, Segye Group, while Eun-ho takes the side of handmade shoemakers who must vacate their building for a XU Cosmetics pop-up store; a sinister case leads the two to trade places.<sup>[2](https://asianwiki.com/Branding_in_Seongsu)</sup> The early episodes center on the XU Beauty brand deal, whose suspected animal testing drives the first conflicts: Eun-ho stumbles on a hidden animal testing lab while inspecting a site, and Na-eon warns him to stay quiet.<sup>[4](https://tv.apple.com/kr/show/branding-in-seongsu/umc.cmc.2jswgbkfnz8wquzf0b66zv8r7?l=en)</sup>

## The Seongsu-dong setting

The drama is set in Seongsu-dong, which it presents as the mecca of branding, a neighborhood where marketing and brand work concentrate.<sup>[1](https://wiki.d-addicts.com/Branding_in_Seongsu)</sup> The real district matches the premise: a former factory area of eastern Seoul that has become known for converted-warehouse cafés, rotating brand pop-up stores, and independent shopping, and that [Cushman & Wakefield](https://www.edgepedia.org/cushman-and-wakefield) describes as Seoul's most rapidly changing commercial district, evolving from an experimental pop-up space into a brand flagship destination.<sup>[8](https://www.koreavisitguide.com/en/neighborhoods/seongsu-travel-guide-cafes-shopping)</sup><sup> • </sup><sup>[9](https://assets.cushmanwakefield.com/-/media/cw/apac/south-korea/insights/research/2025-seoul-high-street-report_eng.pdf?rev=a8ee7bc9bf144bd7992f2e6fb2b0363a)</sup> Academic work on the district's pop-up stores examines exactly the experiential brand marketing the drama depicts as its characters' profession.<sup>[10](https://www.kisd.or.kr/data/thesisData/17356385401.pdf)</sup>

## Release and reception

The series premiered on U+ Mobile TV on February 5, 2024, and ran through March 14, 2024.<sup>[1](https://wiki.d-addicts.com/Branding_in_Seongsu)</sup> Outside Korea it streams on Rakuten Viki, which promoted it as "a delightful romantic romp with a supernatural twist," available by subscription or free with ads.<sup>[5](https://www.justwatch.com/us/tv-show/branding-in-seongsu)</sup><sup> • </sup><sup>[4](https://tv.apple.com/kr/show/branding-in-seongsu/umc.cmc.2jswgbkfnz8wquzf0b66zv8r7?l=en)</sup>
