The storyline was very well done. I'm impressed that this had two main male Chinese actors. I was also impressed that I finally got to see a Chinese drama without romance or competition of female leads for the male lead or vice versa. I love art, the producers were perfect with how their direction regarding sketches, drawings, and what made me very happy is that they showed face blindness having autism. Thank you for bringing attention to autism disorders. Tan Jian Ci who played Shen Yi was excellent with his acting displaying a sketch artist and oil paintings. Very handsome actor. Jin Shi Jia who played Du Cheng, for a minute I thought he was a real detective/police. JSJ was very believable. I thank all the actors/actresses in the characters that they played to make the storyline more believable. This is a rewatch for me!
