The drama DEAR. M is one of the Korean dramas from 2021 that had its airing postponed for quite a long time due to controversy. Park Hye Soo, the female lead, was accused of bullying during school, although she publicly denied the allegations.

This case remained unresolved, forcing KBS to delay the airing of this drama, which also stars Jaehyun from NCT. After four years, DEAR. M finally aired on KBS JOY on April 14, 2025, but only received a rating of 0.1%.

2. A HISTORY OF LOSERS

The drama A HISTORY OF LOSERS is another Korean drama that had its airing postponed due to past issues involving its main actors. Jo Byung Gyu and Song Ha Yoon were both implicated in allegations of bullying during school, tarnishing the image of this drama.

Jo Byung Gyu managed to prove his innocence through legal means, but the case against Song Ha Yoon remains unresolved. This 2022 drama eventually aired in 2025, but audience enthusiasm was low, resulting in disappointing ratings.

3. KNOCK-OFF

The drama KNOCK-OFF became one of the Korean dramas that had its airing postponed due to the involvement of its two main actors in controversy. Kim Soo Hyun was caught up in rumors alongside the late Kim Sae Ron, who was previously involved in a DUI case.

Although the big name of Kim Soo Hyun should have been an attraction, the sensitive issue created significant pressure for the production team. The airing that eventually took place in 2025 failed to create a significant impact in the Korean drama market.

4. A PIECE OF YOUR MIND

Although it is not among the Korean dramas that had their airing postponed due to controversy, A PIECE OF YOUR MIND experienced a reduction in the number of episodes. The drama starring Jung Hae In and Chae Soo Bin only aired 12 out of the initially planned 16 episodes.

Low ratings that only reached 1.4% forced tvN to cut its airing duration. The slow storyline and minimal conflict caused viewers to lose interest, even though the acting quality and cinematography remained well-maintained.

5. DELAYED JUSTICE

DELAYED JUSTICE is also on the list of Korean dramas that were postponed due to a change in cast. Bae Seong Woo was dropped from the project due to involvement in a drunk driving case, creating a stir during the airing.

Senior actor Jung Woo Sung took over the lead role starting from episode 17. Although the drama managed to complete all its episodes, the cast change caused ratings to plummet and public attention towards the drama drastically decreased.

6. SCHOOL 2021

The drama SCHOOL 2021 is a Korean drama that was postponed due to a change in the main cast. Kim Young Dae withdrew from this project, triggering internal conflict and causing filming to be delayed for several months.

After being replaced by Kim Yo Han, the drama finally aired in November 2021. However, the high expectations from the "SCHOOL Series" franchise were not met, with national ratings only around 1%, far below its predecessor.

These are the series of Korean dramas that were postponed, some of which have already aired but received very low ratings. There are still many other recommendations that KLovers can discover by reading articles on kapanlagi.com. Because, if not now, when?
