Definitely one of my top five Korean dramas I have ever watched. From the beginning to the very end of the drama, I personally feel that there are very valuable life lessons to take away from the drama.
1. We don't live just for ourselves but for the people who have supported us and love us.
2. We need to spend less time complaining about the world and the insignificant problems that we feel is world ending, but rather spend time with the people we love the most and pursue what we believe is important.
3. Live everyday the best we can, even if the day sucks.
The story started a bit slow on episode 1 for me, but it picked up pretty well and progressed well to the ending. A lot of heart breaking scenes and also moments to laugh about. Overall, I would give it a solid 10/10. This is one of my first reviews I have ever written about a show of any kind.
