This is the most amazing drama 😍. I've never post any review eventhough I've watched countless of kdrama but seriously this drama is the best. It's not simply just about investigation and crime. It has more than that. The relationship that are potrayed in this drama are very heartwarming and i love everything about it. This drama pretty much makes me cried a lot. I'm 100% recommend this drama. Totally worth watching♥️
