What Is “Potato Research Center” About?

Set in a rural potato research institute hidden away in the mountains of Gangwon Province, Potato Research Center is a unique and cozy workplace romantic comedy.

The story follows Kim Mi-kyung (played by Lee Sun-bin), a passionate 12-year veteran potato researcher, and So Baek-ho (played by Kang Tae-oh), a strict and principle-driven director who arrives after a corporate merger. The two start off on the wrong foot, constantly bickering over research methods and company politics, before slowly falling in love.

The series was directed by Kang Il-soo and Shim Jae-hyun, with writing by Kim Ho-soo—the creative team behind fan-favorite historical series Rookie Historian Goo Hae-ryung.

Domestic Viewership vs. Global Success

In South Korea, the show faced stiff weekend competition, resulting in modest TV ratings:

Episode	Air Date	Korea Viewership (Nielsen)	Notes
Episode 1	March 1, 2025	1.7%	Series Premiere
Episode 8	March 23, 2025	2.0%	Series High
Episode 12	April 6, 2025	1.5%	Finale

While local numbers stayed low, the global response on Netflix told a completely different story. Overseas viewers fell in love with its refreshing setting, charming agricultural humor, and the undeniable chemistry between Lee Sun-bin and Kang Tae-oh.

According to streaming analytics platform FlixPatrol, Potato Research Center rocketed into the Top 10 TV Shows in 52 countries and climbed to #7 globally on Netflix.
