I've seen many comments about being uncomfortable to watch this. It's okay if you don't watch don't spoil for others. The trailer shows it has mature theme and deals with dark side and grey areas of human society. If you like complex characters you will enjoy this. All characters have some negative trait in their characterstics but you can't deny the overwhelming positive sides that reside in them. Qian is the one of the most complex character I've personally seen in bls. He is also very strong willed and stubborn. I'm most excited about his character devlopment.
