This is a tortuous (because the two often short-circuit) love story between a killer (a road killer) and a teacher (a driving school teacher)...
Ye Shuyu, who is always half a beat, and Bai Tian, who is always half a beat, how much current is needed to produce sparks?
Maybe it will be like what is sung in the song,
Half a beat fast and half a beat slow makes it more compatible.
