Romantic Doctor Teacher Kim season 2 is currently in the works! It also looks like an offer is out to Ahn Hyo Seop (Abyss) to take on a lead role. He would play a skilled and cynical first year surgical resident.
Apparently, Han Seok Kyu (Romantic Doctor Teacher Kim) is considering an offer to return and reprise his role, but as of now it appears Yoo Yeon Seok (Mr. Sunshine) and Seo Hyun Jin (Beauty Inside) will likely not be returning.
Romantic Doctor Teacher Kim was about a talented doctor (Han Seok Kyu) who lived as a recluse, but then met some younger doctors and became a mentor to them teaching them about love and life.
Romantic Doctor Teacher Kim 2 will air on SBS.
