I think,this series has the strong plot.We cannot guess the plot.And,the casts star as their characters like reality.All of them are really good at acting.I also love Wang Yibo's acting skill.He is young nevertheless he is talented.He can act with seniors like professional actors.He is really enthusiastic next he deserves to be famous.Finally,there is no fliter using for casts.So,this fact is my most favourite one form this series.Most of the movies use the filter and ut makes the actors and actress to be pale.We can know how much dangerous of the drugs and it makes me feel.The title is extremely good and the world does not wants the drugs.
