This drama is shaping up to be a sure fire hit and fans will certainly be excited to hear more of the season 2 cast members are returning. For Romantic Teacher, Doctor Kim season 3, leads Han Suk Kyu, Lee Sung Kyung, and Ahn Hyo Seob are all confirmed and this week you can add Kim Min Jae to the returnees. Checking the season 3 cast list, basically everyone is coming back so I won’t go down the list but getting so many to return even in supporting roles is quite a feat. The drama is slated to air in early 2023 and will hopefully present fresh new medical stories.
