Best romantic doctor drama ever

wow Dr.romantic is one of the best kdrama ever in the world. the drama is very nice. interesting to watch, some plot have knowledge and new things about real life and will learn by watching from these drama especially season 3 was nice and awesome and interesting too watch some are sad too and love and some may fiction but almost like base in true story too. I can't wait for season 4 ih next few Years later I doubt season 1 to 3 actors going to be in season 4 because in the ending season 3 everyone was coming back .
