Nobody Knows Budget

What Is the Budget of Nobody Knows (2020)?

Nobody Knows (2020) is a 16-episode South Korean crime drama broadcast on SBS, written by Kim Eun-hyang and directed by Lee Jung-heum, produced by Story TV and Studio S. As is standard for Korean primetime drama, SBS and the producing partners did not publicly disclose specific per-episode budgets, but industry estimates for SBS, KBS, and MBC primetime drama in the 2020 production window typically ranged from approximately 700,000,000 to 1,200,000,000 Korean won per episode, equivalent to roughly $600,000 to $1,000,000 in 2020 exchange-rate terms. Across the 16-episode run, the cumulative production cost is estimated at approximately $10,000,000 to $16,000,000.

The series operated within the standard Korean broadcast drama economic model: a network license fee from SBS that covered a meaningful share of production cost, supplemented by an early international streaming sale (in this case to Viki and selected regional partners) and downstream Korean home-video and replay revenue. Korean drama at this scale routinely targets a single 16-episode season with a finite story rather than open-ended renewal, which shapes the production economics.

Key Budget Allocation Categories

Nobody Knows' per-episode production cost was distributed across several core areas typical of Korean primetime crime drama:

• Above-the-Line Cast: Kim Seo-hyung, fresh off her career-defining SKY Castle (2018-2019) role, anchored the series as detective Cha Young-jin. Lee Joon-ho, the 2PM idol expanding into serious drama, took the antagonist role of Lee Sun-woo. The supporting cast included Park Hoon, Ryu Deok-hwan, and Ahn Ji-ho. Lead Korean drama cast at this profile typically commands the largest line item.
• Korean Location Production: The series filmed across Seoul and surrounding Gyeonggi Province, with high school, hospital, police-station, church, and apartment-block exteriors and interiors that required permitting, dressing, and crew time. The mixed exterior-interior shoot drove the standard Korean drama line item.
• Production Design: Detective Cha Young-jin's family apartment, the police station Major Crimes division, the antagonist's church compound, and the high school sets were the four recurring set anchors. Korean crime drama production design typically prioritizes naturalism over stylization, with weekly dressing refreshes.
• Cinematography and Lighting: The series' contemplative, blue-grey visual palette required deliberate lighting design across naturalistic interiors. Korean crime drama tends to favor a slower camera pace than American procedurals, which extends the shooting schedule per episode.
• Music and Score: Original score and licensed needle drops were a recurring weekly line item. The closing theme by Kassy ("Forever Pain") and incidental score from Kim Tae-seong defined the show's emotional tone.
• Post-Production and Delivery: Editorial, sound, music, color, and SBS broadcast delivery were handled through Studio S and partner Seoul-based post houses, with the standard 16-episode delivery schedule.

How Does Nobody Knows' Budget Compare to Similar Series?

At an estimated $600,000 to $1,000,000 per episode, Nobody Knows sat in the mid-to-upper band of Korean broadcast drama, below the highest-budget tentpoles but well above the lower-tier weekend slots. Comparable productions illustrate the range:

• Stranger / Secret Forest (2017, 2020): Budget approximately $700,000 to $1,000,000 per episode on tvN. The Lee Su-yeon prosecutorial thriller is the closest stylistic and budget peer to Nobody Knows.
• Signal (2016): Budget approximately $700,000 per episode on tvN. The Kim Eun-hee cold-case thriller occupied roughly the same per-episode tier and demonstrates the Korean crime-procedural cost band.
• Kingdom (2019-2020): Budget approximately $1,800,000 to $2,000,000 per episode on Netflix. The Kim Eun-hee zombie historical drama, financed directly by Netflix, ran at roughly twice the per-episode cost of Nobody Knows due to its period and creature-effects requirements.
• SKY Castle (2018-2019): Budget approximately $400,000 to $600,000 per episode on JTBC. Kim Seo-hyung's prior breakthrough series, contemporaneous with Nobody Knows in its airing window, ran at a lower per-episode budget and demonstrates the cable-versus-network spread.

Nobody Knows Season Performance and Ratings

Nobody Knows premiered March 2, 2020, on SBS and ran 16 episodes through April 21, 2020. The series airing window coincided with the early-pandemic period in South Korea, which had complicated effects on viewership but did not prevent the show from delivering a steady ratings performance:

• Per-Episode Budget: approximately $600,000 to $1,000,000 across the 16-episode run
• Total Series Investment: approximately $10,000,000 to $16,000,000 across 16 episodes
• Original Broadcast Window: March 2, 2020 to April 21, 2020 on SBS
• Korean Audience and Ratings: peaked at 7.4% AGB Nielsen Korea nationwide rating in episode 11; averaged approximately 5% to 6% across the run, a strong performance in the 2020 Korean broadcast environment
• International Distribution: distributed internationally through Viki (Rakuten), iQiyi in selected territories, and SBS's own international content sales
• Streaming Availability: currently available on Viki, with regional availability on iQiyi and through SBS digital platforms

The series was widely praised in Korean trade press as one of the standout 2020 SBS broadcast dramas and a vehicle that confirmed Kim Seo-hyung's transition from supporting and antagonist roles to top-billed lead status. The 16-episode finite-story format and the strong international Viki audience together delivered SBS and Studio S a profitable single-season production cycle.

Nobody Knows Production History

Nobody Knows was developed at SBS's Studio S in-house production arm and Story TV, with Kim Eun-hyang writing all 16 episodes and Lee Jung-heum directing. Kim Eun-hyang built the script around a long-running cold case as the structural spine, drawing on the procedural-with-character-stakes model that Korean crime drama has refined since Signal (2016) and Stranger (2017).

Casting Kim Seo-hyung as detective Cha Young-jin in mid-2019 was the project's central creative bet. Kim had just completed her star-making run on SKY Castle and was offered multiple competing projects; her acceptance of Nobody Knows confirmed the show as a major 2020 SBS commission. Lee Joon-ho was cast as the principal antagonist Lee Sun-woo, expanding his serious-drama profile after his earlier work in Confession (2014) and Just Between Lovers (2017-2018).

Principal photography ran across late 2019 and into early 2020 in Seoul and Gyeonggi Province, with the Major Crimes Division police-station interior shot at a dedicated Studio S soundstage. The early-pandemic timing of the broadcast window created production-side complications for the final stretch of episodes but did not delay the SBS schedule.

Awards and Recognition

Kim Seo-hyung won the Top Excellence Award for Actress in a Genre/Fantasy Drama at the 2020 SBS Drama Awards for her lead role as Cha Young-jin. Lee Joon-ho was nominated for Best New Actor and Excellence Award honors at the same ceremony for his role as Lee Sun-woo. The series received additional category nominations at the 2020 Asia Artist Awards and Seoul International Drama Awards.

The show was widely cited in Korean year-end critics' polls (Cine21, Sports DongA, MyDaily) as one of the standout 2020 broadcast dramas, alongside Hospital Playlist, The World of the Married, and Crash Landing on You. Its critical and ratings success cemented Kim Seo-hyung's status as a top-billed lead and established Studio S's in-house production capability at SBS.

Critical Reception

Nobody Knows received broadly positive reviews from Korean and international critics. Korean trade press praised Kim Seo-hyung's contained, melancholy lead performance and Lee Joon-ho's shift into serious dramatic territory, with multiple reviewers calling the show one of the standout SBS crime dramas of the late 2010s and early 2020s. The serialized cold-case structure, the careful pacing across 16 episodes, and the emotional weight of the detective-and-boy storyline drew consistent praise.

International English-language coverage on Korean drama review platforms (MyDramaList, Soompi, Asia Pop, KissAsian) was strongly positive, with MyDramaList user scores averaging in the 8.5-out-of-10 range across tens of thousands of ratings. Reviewers noted that the show's thematic interest in adult complicity in child neglect gave it dramatic weight beyond the standard procedural template, and the final-episode resolution was praised by The Korea Times for its restrained refusal to deliver pat catharsis.
