I love the way they act. Specially yibo s face expression are spot on . I have watched six episodes and I like the way story is moving. Two different way to solve a case. One by force and one by brain. Though it’s mystery drama but same time funny too . I like the story line as well as acting skills of leads. Song s character is very powerful as a female inner guard and she is performing it well. As compared to previous drama Wang Yibo s character is based on use of brain rather than fighting skills and he has improved his acting skills a lot. There is more to come and I am waiting for next episode to watch
