So far I've watched 13 episodes, hopefully it'll be as good till the end. Everywhere I see people praising this drama for it's the portrayal of autism, it's great, love it, but that's not what I like most about this drama. What I love most about it, what I think made this drama so good, is how each characters are complicated people, they're all has their good and bad side, all are gray like all of us. Something rare in dramaland. Each episodes share many problematic things in this world that we need to pay more attention to. Each episodes made us think more about social problem that often got shoved to the side. Each episodes made us contemplate more on how we should live our life, be a better person.
