I watched lots of high-ranking Chinese drama during last 2 months, and this one really inspired me.
Never imagine that a crime drama can be good without any inference, but this masterpiece make it through acting, kinship, emotion, close-up film, background light, carefully choosed songs and etc..
I choose to believe in fairy tale ending, but later I feel guilty and choose the other creepy ending due to I find that the speical kid is really really really bad.
Highly recommend crime drama and please google some interpretation after watching, there are lots of hidden details will surprise you again.
