This drama was very powerful! The cast was the standout for me as I believed that the three main leads nailed their roles. Geu-ru played his role perfectly as he had to become a 20 year old with a developmental condition. Hopefully his role brings the viewers to understand the reality of people who may share the same disorder as Geu-ru. Na-mu is the neighbour everyone would love to have. She is very loving and caring for Geu-ru and worries for him as if he is family. Speaking of family, Sang-gu is the uncle of Geu-ru and he is my favourite character in this drama. To witness his character development from the first to last episode was special. You could tell that as he spent more time with his nephew he grew a fond love for him. The story was very intriguing as majority of the episodes focused on the stories of the deceased and what led them to their demise. Each episode did it's part in revealing some lore upon our main characters and managed to connect everything together by the end. The genre of music used in this drama was classical, and the scenes in which they played the pieces eloquently matched the tone of the moment. This show delivers a unique storyline and contains a stellar cast, which in combination creates an impactful drama everyone should experience.
