don't know..but don't think you should waste your time watching this...i bet many of you would think that this is the Chinese version of "my introverted boss",,,which isn't true and the actors totally suck here..their acting is bullshit when they try to pull out something funny........don't think comedy suits it........however it's my opinion...the plot becomes too boring in the middle and they pull out unnecessary stuffs which aren't at all related to anything...however they did nt put much effort in casting the actors and that is why this contains low ratings.....
