It was genuinely captivating for about the first 8 episodes then it began to drag out. I see this alot with kdrama these days. I knew romance was gonna be introduced but the romance kinda ruined it. They spent so much time on unnecessary shots of the couple and totally forgot about the mystery. Tbh after episode 11 they should have revealed that culprit at episode 12. I just couldn't finish it. It dragged out so I dropped it.
