I watched this drama as a part of recommendation challenge and I literally have to thank them for introducing me to this.

To outline the drama it was an absolutely wonderful and interesting watch.
There was a bit of everything for me that worked here - action, romance with both strong male and female lead and a bit of suspense and drama. The story kept me intrigued and invested till the very end. Each and every detail or clues in every episode somehow made sense at the end. I couldn't find any story loopholes. Tbh story isn't very unique but it is put together to almost perfection. You would really have to nitpick (which I am not gonna do :D)

The acting by all the cast members were perfect! The romance arc between the ML and FL is simply beautiful. The chemistry between them is FIRE! No nonsense! Just 2 adults trying their best to be together and handle things maturely. The OST was decent too. 

All is all , a great watch!
