I started watching this because of song kang
I am not into this series actually but After seeing so many romantic dramas and crime dramas I wanted to see something REFRESHING & Good story
If you want to have something with good emotional story and perfect acting then go for this one

IF YOU ARE FACING PROBLEMS IN REAL LIFE THEN YOU SHOULD DEFINITELY WATCH THIS DRAMA AS IT MIGHT GIVE YOU COURAGE TO SOLVE YOUR PROBLEMS..

Song kang and grandpa relationship is nice and side character's development is also nice and there are heartwarming scenes
You might need to have a tissue in your hand too
These days I stopped crying after seeing so many korean crime dramas but after a long time NAVILLERA made me cry again


I am still watching this so I Will update more soon
[now updating]

Now after completing watching it I can only say one thing if you want something about real life [ not like supernatural or other genres ] then you should definitely watch this. You will definitely like this.
And if you dont like dance then dont stop watching it becoz I also dont like dance but didnt I like it
...who know you might like it too..//!!
