Can you top this Korean drama viki hit list?

Viki has become the default destination for Korean drama viewers who want fresh releases the same week they air in Seoul. The platform’s mix of free tiers, rapid fan subtitles, and exclusive premieres keeps its charts moving fast, so the current list of most-watched titles reflects both 2025 breakout hits and a few evergreen standouts that still rack up replays.

Platform momentum

Viki’s parent company reported another quarter of double-digit growth in North America and Latin America, driven almost entirely by Korean content. Executives credited the surge to day-and-date releases and the free-with-ads tier that lowered the barrier for first-time viewers.

During the September 2025 K-Drama Day event, Viki unlocked dozens of episodes across its top titles for 48 hours. Traffic spiked 40 percent, and several shows that had slipped out of the weekly top 10 re-entered the charts within a single weekend.

Romance dominates the catalog, but Viki’s 2025 slate also tested action and fantasy hybrids. The experiment paid off: non-romance titles captured 28 percent of total viewing hours, a record for the platform.

My Dearest Nemesis

Mun Ka-young and Choi Hyun-wook play former online gaming rivals who collide again as boss and intern sixteen years later. The revenge-romance premise caught fire on TikTok edits, pushing the series to the number-one spot in 136 countries during its run.

Viki’s own year-end recap listed the drama as its most-streamed original of 2025. International viewers praised the brisk pacing and the leads’ crackling chemistry, two factors that helped it outrank bigger-budget cable productions.

Its success also boosted older revenge-tinged titles in the catalog; searches for similar stories rose 65 percent the week after the finale aired.

Love Scout

Han Ji-min plays an absent-minded CEO whose life runs on the organizational genius of single-dad secretary Lee Jun-hyuk. The workplace rom-com format feels familiar, yet the series updated the trope with credible parenting scenes and realistic power dynamics.

Regional reports from Brazil showed Love Scout edging out My Dearest Nemesis in total hours viewed during November. Viki staff polls ranked it the most memorable drama of the year, citing Han Ji-min’s layered performance.

Because the show leaned into everyday chaos rather than high-gloss melodrama, it drew first-time viewers who later binged the back catalog of office romances already on the platform.

Study Group

Webtoon fans recognized the premise immediately: underachieving students band together in a school ruled by gang violence. Hwang Min-hyun’s shift from idol actor to brooding leader broadened the drama’s reach beyond the usual romance audience.

Viki highlighted Study Group in its December 2025 staff picks, noting that action sequences accounted for 35 percent of clip views on social media. The series proved that fight choreography can trend as aggressively as kiss scenes.

Its school-setting relatability also sparked Reddit threads comparing it to American teen dramas, a crossover conversation that funneled new subscribers toward Viki’s youth-skewing catalog.

The First Night with the Duke

A college student wakes up inside her favorite historical web novel and must rewrite the plot to survive. The meta premise let writers poke fun at genre clichés while still delivering sweeping gowns and palace intrigue.

Regional lists from Brazil and Mexico placed the fantasy romance inside their monthly top five on Viki. Its book-to-screen appeal mirrored the success of similar adaptations on Netflix, yet Viki retained exclusive global rights outside Asia.

Viewer forums credit the drama with reviving interest in the original web novel, whose English translation climbed Amazon charts the week after the finale dropped.

Dear X

Kim You-jung portrays a scarred woman who weaponizes charm and manipulation to climb the social ladder. The thriller marked a tonal shift for Viki’s 2025 lineup and still competed closely in staff polls with lighter romances.

Its psychological focus drew viewers who typically skip straight romances, widening the platform’s demographic. Social media clips of the lead’s chilling monologues accumulated millions of views within days of each episode release.

After the finale, searches for “dark Korean drama Viki” increased 80 percent, signaling appetite for more non-romance entries in the coming slate.

Taxi Driver Season 3

Lee Je-hoon returns as the head of a secret taxi collective that dishes vigilante justice when the legal system fails victims. The franchise’s third season stayed lean, focusing on three self-contained cases rather than an overarching arc.

Soompi’s December 2025 top-five list on Viki included the season, underscoring its consistent pull with action fans. The familiar format let viewers jump in without homework, a selling point for casual weekend binge sessions.

Renewed interest in earlier seasons pushed the entire Taxi Driver catalog back into the global trending row for the first time since 2021.

Last Summer

Lee Jae-wook and Choi Sung-eun play childhood friends who unearth family secrets during a reunion trip. The drama’s quiet emotional register contrasted with flashier 2025 titles but still landed in Viki’s year-end highlights.

K-Drama Day free unlocks helped the series reach viewers who rarely pay for on-demand content. Word-of-mouth spread through parenting forums, where audiences related to the divorce and reconciliation themes.

Its understated marketing relied on cast chemistry clips rather than glossy trailers, a strategy that Viki plans to repeat for similar mid-tier originals in 2026.

Moon River

Kang Tae-oh and Kim Se-jeong headline a fantasy romance about a crown prince who has lost his smile and a traveling merchant who has lost her memory. Lavish sets and a sweeping score positioned the drama as Viki’s prestige winter event.

Soompi’s December top-five roundup cited strong international retention past episode six, unusual for fantasy entries that sometimes lose viewers when lore piles up. The leads’ prior global hits gave the series an instant recognition bump.

Behind-the-scenes vlogs posted on Viki’s official YouTube channel racked up views comparable to the episodes themselves, extending engagement beyond the platform.

Evergreen standouts

Guardian: The Lonely and Great God and What’s Wrong with Secretary Kim still dominate all-time fan-voted lists on Viki. Their continued presence in the top twenty proves that star power and rewatch value outlast release windows.

Both titles benefit from algorithmic recommendations that surface them to newcomers who finish a 2025 romance and want tonal comfort food. Viki’s decision to keep them on the free tier guarantees a steady flow of new eyes.

Platform data shows these older hits generate 15 percent of total monthly viewing hours, revenue that subsidizes riskier experiments with non-romance genres.

What the charts signal next

The current mix suggests Viki will double down on romance while carving out protected slots for action and thriller experiments. If the pattern holds, 2026 viewers can expect fewer gaps between seasons of established franchises and quicker pickup decisions for web-novel adaptations that test well in the first month.
