I'm adding this review only because the synopsis is vague and doesn't help you decide whether to watch it or not. The tags however are helpful. I googled Ripley's Syndrome which is described as a antisocial personality disorder where one makes up grandiose lies and believes in this distorted reality. The person feels no shame or sympathy for his/her victims. This last point however doesn't quite fit the depiction about Anna as she does seem to experience guilt and shame.

From this, you can kind of guess the storyline. I'm going to leave it here as I've only watched 2 episodes. However I will add that Bae Suzy is again the consummate actor. She has once again turned a flat 2D script into a 3D person with complex and often conflicting emotions and motivations, and really made the character hers. I look forward to watching the rest of the series, thankfully only 8 episodes in all, and will be back at the end with a deeper review.

Updated: I have now finished watching the whole series. 8 episodes cut down to 6 and I can say that the last 2 episodes were the weakest in the whole show. Clearly there's been heavy editing to fit the last 4 episodes into 2 and for no apparent reason. It's puzzling that they needed to cut; were that ratings bad? If ratings were so bad, why are they going to broadcast and extended version in August?

I have downgraded my overall rating because of these last 2 episodes. Pity. I certainly won't be watching the extended edition in August.
