Everyone’s watched Crash Landing on You. Fewer people know that Ji Chang Wook played a bodyguard-turned-assassin’s-target years before he became a household name, or that Kim You Jung once played a blind astronomer’s love interest in the Joseon era. That’s the whole point of Viki’s K-Drama Day — a celebration built specifically to pull underrated shows out of the algorithm’s shadow.
To mark the occasion, Viki curated a “Hidden Gems” collection spanning romance, thriller, sci-fi, and everything in between. Here’s the full rundown, elaborated.

The Standouts, Explained

For period-drama lovers: Knight Flower and Lovers of the Red Sky both use the Joseon setting to hide something bigger — a vigilante widow in one, a court painter defying gender norms in the other. If you enjoy the aesthetics of a historical Korean drama but want more bite than a typical royal romance, start here.
For thriller fans: The Scarecrow spans three decades to track two men bound by hatred and circumstance, while Strangers From Hell leans fully into psychological horror — Yim Si Wan’s descent into paranoia inside a decrepit dormitory is not for the faint of heart. The K2, meanwhile, blends bodyguard action with political conspiracy for a more mainstream thrill.

For rom-com comfort watches: Suspicious Partner, 1% of Something, and Extraordinary You all deliver classic enemies-to-lovers or forced-proximity tropes, but with enough twists — a wrongful murder case, a contract relationship, a character literally rewriting her fictional fate — to feel fresh rather than formulaic.
For something quieter: Do You Like Brahms? and At a Distance, Spring Is Green trade high-concept plots for grounded, slow-paced stories about music, ambition, and growing up. Good Partner does something similar in a legal setting, following two divorce lawyers on opposite ends of their careers.
For younger, lighter watches: Spirit Fingers and Duty After School round things out — one a gentle webtoon adaptation about a drawing club, the other a surprisingly fun sci-fi twist on the high-school genre, complete with alien invasions.
Why “Hidden Gems” Actually Matters?
Streaming algorithms tend to recycle the same dozen titles because they already have views. A curated collection like this does the opposite — it resurfaces shows with strong writing and loyal fanbases that never broke into the mainstream conversation. If you’ve already burned through the obvious starter-pack dramas, this list is basically a cheat code for your next binge.
Speaking of starter packs — if you’re newer to K-dramas and want the classics that hooked most fans first, TechnoSports has a solid breakdown of the K-dramas everyone blames for their obsession, worth bookmarking alongside this list.
