Jang Ki Yong is returning to MBC as a banker with no connections. On October 19, 2026, the broadcaster named him and Oh Jung Se as the leads of an office drama set inside a bank. Tenasia reports it is his first MBC drama in about nine years .
What did MBC confirm about Law of the Line?
On October 19, 2026, MBC announced that Jang Ki Yong and Oh Jung Se will lead Law of the Line (Korean title 라인의 법칙), a Friday-Saturday drama scheduled to air in the first half of 2027. Soompi reported the pair as "confirmed as the leads" . Right now, the casting and a broadcast window are the only confirmed details.
Quick Answer: On October 19, 2026, MBC confirmed Jang Ki Yong and Oh Jung Se as the leads of Law of the Line (라인의 법칙). It is a Friday-Saturday office political drama set in a bank, and it is due on MBC in the first half of 2027. MBC has not yet announced a premiere date, episode count or time slot.
Korean outlets describe the broadcast window as 2027 상반기 (first half of 2027) or 내년 상반기 (first half of next year). Etoday , Singlelist and Financial Post all report this window. Tenasia reported the same casting on the day of the announcement .
Here is what has been confirmed and what has not been announced:
- Confirmed: Jang Ki Yong and Oh Jung Se as leads, the MBC Friday-Saturday slot and a first-half-2027 broadcast window .
- Confirmed: the setting. According to Soompi, the story takes place at a fictional bank, Nara Bank (나라은행) .
- Not yet announced: the exact premiere date, the number of episodes and the time slot. Treat any specific date you see online as unverified until MBC announces it.
- Not yet announced: any international streaming partner.
English-language fans can follow the news through Soompi and MyDramaList News, which both covered the casting . Indonesian outlets Okezone and Viva also reported it. All of these reports repeat MBC's own announcement. None of them adds an independent date or new production detail.
What is the story: an office political noir inside a bank?
Law of the Line is an office political noir, the term Korean outlets use for it (오피스 정치 누아르). It is set inside a bank. A low-ranking employee with no backing and no connections uses political instinct and negotiating skill to upset the bank's internal power structure . The bank is not a backdrop for romance or a family saga. It is the arena where the story's battles are fought, and the people working inside it are the story.
An "office political noir" is a workplace drama whose main conflict is the struggle for power inside one organisation, told in the darker, more strategic tone of noir. There are no gangsters or crime bosses. The stakes are promotions, appointments and control of the institution. Etoday and Topstar News both use the same genre label for the series .
According to Soompi, the bank is called Nara Bank, and the plot will cover:
- Fights over management decisions at the bank
- Fights over personnel decisions, meaning who gets promoted, moved or pushed aside
- Rivalries and betrayals among factions inside the organisation
The Korean promotional wording sums up the angle. It calls the show a "practical introduction to office politics" (실전 사내 정치학개론) about a banker with "neither connections nor backing" (줄도 빽도 없는 은행원) . The phrase 줄도 빽도 없는 is everyday Korean. 줄 (jul, "line") means the network of seniors a worker attaches themselves to, and 빽 (ppaek, from the English "back") means influential backing. Saying someone has neither is a familiar way of describing an outsider in a Korean company. That line of patronage seems to be what the English title, Law of the Line, and the Korean title, 라인의 법칙, point to.
This is also where the "as a bank" hook in the headline comes from. Jang Ki Yong is not playing a bank. He is going back to MBC in a story where the bank is the whole stage: its hierarchy, its factions and the race for its top job. The confirmed details stay inside one institution and focus on how power moves between the people in it. That fits the premise of a newcomer with no backing reading the room and negotiating his way into a fight he was never expected to join .
Beyond this premise, MBC has not released a synopsis, episode outlines or a teaser. Nothing has been confirmed about how the factional story plays out across the season or how it ends. Fans should treat any detailed plot summaries circulating online as unofficial until the broadcaster publishes more.
Who plays whom: Tak Do Il vs. Chun Kyung Ho
Jang Ki Yong plays Tak Do Il (탁도일), a bank employee with no connections, and Oh Jung Se plays Chun Kyung Ho (천경호), a senior executive who becomes his rival. MBC named both actors as the leads on October 19, 2026. Soompi reported them as "confirmed as the leads" . Etoday describes the contest and strategic moves between the two men as a central conflict of the series . Tak Do Il has no institutional backing. Chun Kyung Ho is close to the top of the bank. Both men came into banking without elite credentials, and this shapes how each of them plays the game.
Tak Do Il works at the fictional Nara Bank (나라은행), according to Soompi . He graduated from a regional university (지방대) and has no notable background or connections inside the organization. His strengths are reading the room and negotiating. Those skills let him upset the bank's internal power balance .
Tenasia presents Tak Do Il as a clever, cheeky character. It says the role is a change from the romantic-lead image Jang Ki Yong built in earlier dramas . That is Tenasia's description of the casting. Nobody has seen the performance yet, because MBC has not released footage or a teaser.
"줄도 빽도 없는 은행원" ("a banker with neither connections nor backing") — Korean promotional wording for Tak Do Il, as reported by Top Star News and Tenasia
Oh Jung Se plays Chun Kyung Ho. This is Soompi's romanization; Korean outlets write the name 천경호, which can also be romanized as Cheon Kyung Ho . He has only a high school education but has risen through the ranks. Korean media call his story a 고졸 신화, or "high-school-graduate success story." He is now seen as a leading candidate to become the bank's next president . Outlets give his current post in different words, so this article calls him a senior executive and does not name a specific title.
| Character | Actor | Background | Role in the conflict |
|---|---|---|---|
| Tak Do Il (탁도일) | Jang Ki Yong | Nara Bank employee (per Soompi); regional-university graduate; no notable connections | Outsider who uses negotiation and political instinct to disrupt the bank's power structure |
| Chun Kyung Ho (천경호) | Oh Jung Se | High-school graduate who rose through the ranks (고졸 신화) | Senior executive and leading candidate for bank president; Tak Do Il's rival |
Only these two roles have been announced so far. MBC has not named any supporting cast. It has also not said whether other executives or factions will get their own lead characters. International outlets, including MyDramaList News, repeated the same two-lead announcement and added no further casting .
Why is this a return for Jang Ki Yong after nine years?
Law of the Line is Jang Ki Yong's first MBC drama in about nine years. That gap is where the title of this article comes from. Tenasia reported the return on the day of the casting announcement . It named his last MBC drama as Come and Hug Me (이리와 안아줘), which aired in 2018 . MBC plans to air the new series in the first half of 2027, so he will have been away from the network's dramas for close to a decade .
The nine years refers only to MBC. Jang has kept working in dramas during that time. Coverage of the casting lists these titles as part of his body of work:
- Search: WWW
- Now, We Are Breaking Up
- The Atypical Family
Tenasia and MyDramaList News both mention these shows in their reports. The casting coverage does not give their broadcast years or networks, so this article leaves those details out. Readers who want them can check each show's official page.
The second change is the kind of role. Korean coverage frames Tak Do Il as a departure from the romantic leads Jang is best known for. According to Tenasia, the character is clever and a bit cheeky. He works at a bank with no connections and no backing. Rather than carrying a love story, he gets ahead by reading situations and negotiating his way through the bank's internal politics. The genre is also new for him: Korean outlets describe the series as an office political noir (오피스 정치 누아르), a tone unlike the romance-driven dramas his fans have mostly seen.
The return is notable for two concrete reasons:
- Network: his first MBC drama in about nine years, coming after Come and Hug Me in 2018
- Role type: a regional-university graduate who works his way up through office politics, not a romantic lead
So far, that is all the coverage confirms. MBC has not said anything about how the role came about, and it has not released teaser footage, a poster or a premiere date. No outlet has reported comments from Jang about the project. Anything about how the role will land with viewers is guesswork until the first-half-2027 broadcast. Until MBC shares more, fans have the casting, the character outline and the nine-year gap to go on.
Who is making it: director, writer and creator
Three people are named behind "Law of the Line." Kim Sung Yong (김성용) is directing, Eun Ki Baek (은기백) is writing the script, and Kang Eun Kyung (강은경) is attached as creator. These are the credits MBC gave when it announced the casting on October 19, 2026, according to Soompi . Korean coverage gives the same names. Tenasia lists the director and creator , and Etoday lists all three .
Here are the roles as reported:
- Director: Kim Sung Yong (김성용). Soompi, Tenasia and Etoday all name him as director .
- Screenwriter: Eun Ki Baek (은기백), who writes the script, according to Soompi and Etoday .
- Creator: Kang Eun Kyung (강은경), a writer attached to the project as creator, according to all three outlets .
In Korean dramas, the creator (기획 or 크리에이터) credit usually goes to an established writer who shapes the concept and oversees the project, while a separate writer drafts the episodes. That split explains why Kang Eun Kyung and Eun Ki Baek have different credits here. The announcement does not say how the two will divide the work.
This article leaves out the team's earlier credits on purpose. English and Korean reports give different title wording for some of the director's and creator's past shows, so we are naming them by role only until the credits can be matched cleanly. Fans who want to look up their earlier work can search the Korean names above on the original Korean articles.
The production company is also unconfirmed. Some search summaries of Korean coverage name production studios, but we could not find that detail in the articles we checked directly. Treat any studio name you see as unverified until MBC or the producers confirm it. Production stills, a script reading and other behind-the-scenes updates have not been announced either.
How and when can international fans watch it?
MBC will broadcast Law of the Line in its Friday-Saturday drama slot in the first half of 2027 . That is everything confirmed about the release so far. There is no premiere date, episode count or exact time slot yet. No streaming service or international platform has been named either. If a site gives you a date or a platform before MBC does, it is guessing.
Korean reports describe the release window as "2027 상반기" or "내년 상반기." Both mean the first half of next year . For now, that leaves a six-month window from January to June 2027. Read it as a target. It is not a schedule yet.
Here is what is known and what is still open:
- Confirmed: an MBC terrestrial broadcast in the Friday-Saturday slot, planned for the first half of 2027 .
- Not yet announced: premiere date, number of episodes, broadcast time, and any streaming or overseas distribution partner.
- Also unannounced: teaser trailers, posters, a script reading or a press conference. These usually come before a premiere date, so you can use them to tell how close the release is.
To keep track of the show:
- Follow MBC's official drama channels. The broadcaster announced the casting and will announce the schedule.
- Check English-language coverage on Soompi and MyDramaList News. Both covered the October 2026 casting news.
- For faster updates, Korean outlets such as Tenasia often report schedule news before English sites. A browser translation tool is enough to follow them.
Searching works better if you use several versions of each name. The Korean title is 라인의 법칙, and some outlets add "The" to the English title. One Indonesian report calls it The Law of the Line . Oh Jung Se's character also has more than one romanization. Soompi uses Chun Kyung Ho, and Korean sources write 천경호, which also appears as Cheon Kyung Ho or Cheon Gyeong Ho . These are different spellings of the same character, not different characters.
In short, plan for a Friday-Saturday MBC drama sometime between January and June 2027. Wait for MBC's official premiere announcement before you mark a date. Once MBC names a premiere date or a streaming partner, we will update this page.
