I went in for 柯佳嬿 who played the first female lead, Shen Xi, and started to like 翟子路 as Chen Mo Bai. The story at the first 5 eps was a bit too slow, i admittedly fast forward few times, but not when the two leads are together. You can trust 柯佳嬿's acting, very expressive eye and emotion. 翟子路's acting is also improving by each episode. The focus is not too much on love story, but has some technicality about racing and shots are entertaining. The story line also developed very well - and we can see the characters' development and changes in a positive way. I also liked most of the female characters: Chen Mo Fei (Mo Bai's sister), Chen Mo Bai's childhood friend (the VC representative),
