My opinion about this drama : it is 100% related to the lives of young people nowadays who wants to start a career where everything starts from doubt and pessimism and then there is a failure and a wrong decision..that’s natural ! everyone will definitely experience that steps.. that's why dosan and dalmi characters are made like that. And slowly as the time goes by they will get through it and succeed in the end 👌🏻 . Also, there are so many lessons and morals that we can learn from this drama to make us more passionate and have dreams !
