Let me start off by saying this is the best k-drama i have ever seen. The character communication, development, and chemistry is very well done. The scenery and shots are done with a goal in mind. Every character has a deep backstory and there is no character that is evil or good. It is very reflective of everyday people living through their everyday problems. It shows how a single person can give you enough strength to keep going. From the Grandma to the Bartender, it shows the daily thinking and behaviour of a person. Although the ending was a bit quick and time skips are not my favourite thing, it reflects on real life rather than creating a typical happy ending to please the audience. The emotional scenes are so well done and the acting is the off the charts. The love between the brothers was my favourite relationship. The music also reflects the moment very well. It is a must watch that will keep you wanting more.
