K-drama fans are buzzing after reports claimed Lovelyz’s Jeong Yein is set to step into a major role on “The Trauma Code: Heroes on Call.” But before you get too excited, both her agency and Netflix have pumped the brakes on the story — here’s the full picture.

What Sparked the Rumor?

On September 23, Korean outlet MyDaily reported that Jeong Yein had been selected to take over the role of Cheon Jang Mi, a character previously played by Ha Young, for Seasons 2 and 3 of the hit medical drama. According to the report, production reportedly held auditions specifically to fill the role after Ha Young’s exit.

Why Did Ha Young Step Down?

Ha Young left the series following controversy tied to allegations about her family’s history involving pro-Japanese ties — a sensitive issue in South Korea that has ended other celebrity roles in the past. Her departure left a key casting gap the production needed to fill before filming resumed.

What Do the Denials Actually Mean?

Jeong Yein’s agency, SUBLIME, firmly denied the report, stating there have been no discussions regarding her joining the series. Meanwhile, a Netflix representative offered a more open-ended response, confirming that casting talks are ongoing but nothing is finalized. This kind of dual response — a flat denial from the agency paired with a cautious “nothing confirmed” from the platform — is common in K-entertainment when negotiations are still fluid.

About the Drama
