This is not a typical k-drama. Story of people who are struggling in their life, irrespective of their financial status. Amazing story line and acting voilà. IU has beautifully played the character of Lee Ji-an. There are only a few Idol who can sing and act good, she is good in singing as good as in acting, and Lee Sun Kyun is an amazing actor. I have watched his work, coffee prince, Parasite and The Advocate: A Missing Body with Kim Go Eun etc. All are drama and movies are must watch for everyone.
