Story : It's really great, although another drama had the same concept but this is way better and refreshing, I didn't had much expectations from this drama but I'm glad that gave this a try. Acting/Cast: It's great in my opinion, many are criticising Kang Daniel for his acting or saying that it's unfair for the female lead as she is a experienced actor but I personally think both of them are doing great, Kang Daniel might be new in the acting industry but he did do justice to the character, his character is kinda serious also he had less screen time in the first few episodes but I think his character is developing, love the cast. Music : I loved the ost, I have nothing else to say. Rewatch Value : For me I can watch this as many times I possible can, It's great, no matter how manytimes I watch it, it's still refreshing, Love it. Overall : Great one, if you are not watching this drama then you are missing out big time. Highly recommend.
