It's a very intriguing story. FL and ML solve mysterious deaths. The change of the FL is also very interesting. Some may not like it, because the actress who played the FL in the first episodes is also very likeable. Both actresses made a very good impression on me.
I have watched the drama to episode 7. I can't wait till the next episode is aired.

The story between the FL and the ML got me. The FL leads' tragical life.Her families' unsolved deaths which were tarned and presented as her father's betrayal to the state.

All seem to slowly unwind like a big knot giving small hints episode through episode. - We still have to watch many more episodes.-

The ML truly faithful love for the " believed dead" FL is shown very clearly. Although he at first seems to show no emotions, he cares a lot and hides every feeling very well behind a carefully put on passionless mask.
