This show is fantastic. Stigmas in society, such as mental health issues and suicide, are addressed here. Every line of dialogue from the characters is deeply ingrained in the viewers' hearts. There is no episode in which you will not cry because it is so true to life. There will be parts that make you laugh, but you will also learn a lot. It's also a great chance to see how Rowoon's personality changes here, demonstrating his versatility as an actor. They were all fantastic!
