This maybe a Psycho-Thriller/Crime/Suspense but all I get is the Psycho part, it's creepy with almost no suspense at all with a lousy police system.

From the get go, you'll already know who's the sexual predator hiding in an online dating app.

In their attempt to make it look mysterious, I think they didn't incorporate enough subplots to the story. All we know is that the FL is a young genius that developed an online dating app. Then there's her friends; a detective who'd been a victim of a sexual predator and a shaman who's willing to go beyond measures to help a friend.

The actors did good on their part. The musical scoring and OST were ok. All in all, it's an ok show. Nothing spectacular about it though.

Would I rewatch this? Not ever..
