This drama is so full of humanity and of course tears. DON'T SAY YOU DIDN'T GET WARNED. It is both sad and happy. Just like when Geu-Ru's mom said that tears are drops of happiness coming from your eyes, you will feel happy and get reminded that while in so many times, the world can be so cruel, there are still some people around us who never forget compassion no matter the burdens they bring. This drama is filled with life lessons and that kindness doesn't need prerequisites. I'm not Korean so I'm not in the position to judge the acting since I just solely based my understanding through the subtitles but I want to say that every character is so well-placed. Everything that comes from their mouth could stir a lot of emotions. How can this drama be so good even if almost all the characters are kind. It has made me realize that a drama doesn't need vicious antagonists to put emphasis on the protagonists. I admire the writer for such a unique plot and for letting the world know that we should not fail to honor the people who have a job that could be odd and beyond our understanding as to why they have that kind of job but still wholeheartedly do their best to give the best service. I hope to see more of this kind of drama and I hope for season 2.
