Natural, quirky, sweet, thoughtful and emotional. This is such a cathartic drama. A great show about what it means to live according to your values and to be an adult and to grow as a person. So enjoyable to watch. Even when things were difficult and wrenching, I still enjoyed it and felt comforted by it. I heard people criticize it and say it was boring, but it simply had a pace that was slower and more character-driven, and had lots of subtle, quiet moments. The lead couple is compelling, adorable and has incredible chemistry, as does the romance between the second leads. Every character, even the secondary ones, feels interesting and fresh. Ki Seon Gyeom is my new crush, probably forever. Also, Shin Se Kyung was EXCELLENT in this and I just wanted to give her a shout-out because the last thing I saw her in was the Bride of Habaek which was just so awful that I was basically put off of her for years, but my love has been rekindled! That is the power of Run On.
