I had always been a big fan of whodunit and detective shows. I am so glad that I gave it a try and I hope more people watch this masterpiece. The show started with a dead woman in her condo at Horizon Tower, who is possibly murdered. Each suspect were given screen-time of two episodes, in which they were interrogated by the main leads who are detectives. The last couple of episodes were dedicated to the POV of the victim herself. All of the suspects stated their alibi to prove their innocence in the case. At the same time, we get to deep dive into the victim's life...which helps us to form our own judgement against the suspects and the victim. Ep. 8 was very traumatizing. In fact, every episode made me cry and the storytelling was in such a way that you would start pitying some characters. This drama also talks about some dark topics like sexual abuse, child abuse, domestic abuse, mental health issues and so on. In the end, everything was tied perfectly. Though I would have liked to see the culprit suffer more for everything that was done by them. Each character had their own flaws and shortcomings, their own story that they want to project to society and their own dark secrets...which makes them very realistic and relatable.The piano score was the best in this show, which started just in the first five minutes of the first episode. All the background scores were pretty good, with a hint of dramatic note in them. The English OST was also perfect.Every actor/actress did a solid acting job. I had never seen Angelababy's performance before and I was astonished by how well she played the victim role. Amazing cast and outstanding performance.PLEASE WATCH THIS DRAMA, HIGHLY RECOMMENDED. YOU WILL BE MISSING A MASTERPIECE IF YOU DON'T WATCH IT!
