The doctor is back, the romantic teacher on that is! SBS has kicked off the promo circuit for Romantic Teacher, Doctor Kim 3 (Dr. Romantic 3) which reunites the entire cast from season 2 with Han Suk Kyu, Lee Sung Kyung, and Ahn Hyo Seob as the leads along with the sprawling broader supporting cast of familiar faces. The drama has confirmed the premiere date of April 28th so a month from now and the first promos are a lovely quiet poster and stills of the three leads back in medical action in scrubs and white coat.
