The Trauma Code: Heroes on Call seasons 2 and 3 have found their new nurse. Ye-in Jeong of K-pop girl group LOVELYZ will join the cast of the hit webtoon-based live-action series as nurse Jang-mi Cheon, stepping into the role previously held by Ha-young.
Entertainment news site Variety reported the casting news, confirming that Jeong is on board for both upcoming seasons, which are currently in production and will stream exclusively on Netflix. Premiere dates for the new seasons have not been announced.
Jeong replaces Ha-young, who left the series following controversy over allegations that her great-grandfather collaborated with Japanese colonial authorities. The recasting closes the loop on a saga that has shadowed the show since the new seasons were confirmed.
