Nice drama but very underrated. You can see the versatility of Ji Chang Wook as an actor. He isn't just limited to action roles. Choi Sooyoung is a great match for her role too. Both mains give off a very good chemistry. As for the drama itself, every episode gives an overwhelming emotion that stirs the hearts of the viewers. There is a lesson you can learn and the drama shows what experiences people have been going through their lives and how they get through it with the support of the people around them. It pains my heart but I love it.
