The Potato Lab

“The Potato Lab” (Korean: 감자연구소) is a 2025 South Korean rom‑com series on tvN (and on Netflix internationally) starring Lee Sun‑bin and Kang Tae‑oh. Across 12 episodes airing weekends from March 1–April 6, 2025, this quirky drama unfolds in a scenic mountain‑valley potato research institute.

Plot Synopsis

Nestled in a tranquil mountain valley, the story revolves around a rural Potato Research Institute (aka “Potato Lab”) where Kim Mi‑kyung has spent 12 devoted years. Proud of her unconventional obsession – she’s even breeding a special potato named “Mi Gyeong” – she’s beloved locally but seen as eccentric.

Enter So Baek‑ho: a cold, efficient Wonhan Retail efficiency expert sent to restructure the lab after Wonhan acquires a potato chip company. Their first interactions are turbulent – Mi‑kyung sees him as a soulless bureaucrat; he views her lab as outdated.

Their dynamic oscillates between fierce workplace rivalry and unexpected affection—think a whirlwind “tornado potato” romance.
