It's the first time I felt like writing a review, seriously this drama is one of the best I've ever watched, so heartwarming, simple and intricate at the same time. Characters were amazingly conceived, they are dynamic and grow throughout the story. The actors were great to depict all changes from childhood to adulthood. Dramatic moments made me cry, they felt so real, like I was watching that scene in real life. Great concepts and developing. Everything about this drama is just perfect, feel like I'll rewatch it soon.
