Not a typical Korean Drama

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.

I am in the trap.

I feel so emotional whenever I watch the drama, even the clips on YouTube/Facebook. Have watched this drama, don't know how many times, not sure.
The two main characters are complicated and simple at the same time. Love the chemistry between the two.
I just love the lead actress Kim Go Eun.
Have watched most of her work. Lead actor Park Hae-jin, played the role so nicely, coldness in his eyes in some of the scenes, is breathtaking.

I would recommend to watch this drama for the two lead characters.
