This drama introduced me to K-drama world

This was my first ever K-drama that I accidentally watched one day and after that I became an addict of K-dramas. I knew nothing about Korean dramas at that time but due to this, I regularly watch all the current shows and previous ones.

The acting and story is amazing once you start, you can't resist yourself from watching it till the end, all the actors played their role so realistic that I even cried at the end ??

Overall the drama is Perfect to recommend someone who likes action dramas
