I like that most if the character is smart especially the female lead. She is really good in survival and the dynamics between the female lead and the other roles is great. The earlier episodes maybe seems as slow but the mysterious surroundings the male lead make me stay until the end for this drama. I like that the bad person in here really smart so that the police need to be smarter to catch them.

Zheng Ye Cheng did a good job in portraying this character. His charisma and I like to see him more in the future!
