The trailer seems promising, but this drama's got some loopholes and it was a letdown. The suspense wasn't there, and it wasn't thrilling. I got bored after watching ep 3 onwards. There were a lot of boring dialogue and fillers. The drama could have been better if the script was better. I didn't understand why the need for the neighbor's character when she didn't do anything major in the drama, or no major explanation for the high school girl that got murdered. Or what's with the husband and his relationship with the high school girl. Also, no explanation for why the sister's dead. Like did she get killed or was she died by suicide? There were so many missing things and loopholes. It was disappointing.
