One of the top drama I've watched

This is one of the top kdrama I've watched!
To be honest I watched this just because of Song Kang and because I saw it a lot last year thru social media... and I can easily say that if the thing I've watched made me cry and laugh this is best production!
It kept me on the night and I was waiting to watching next and next episode...
Even tho I gave it 9,5☆.. just because there was something missing... the whole production, music and actors have my 10☆
I will definitely watch My Demon again in the future
