WHY CV'S CHANGED THE COMPLETE PLOT?

Hello everyone,

Till 150th Episode, it was all about Pari finding Maa in her Saasu Maa. And now, we don't even get any scenes of Pari and Maa Saab? Why did CV's change the whole story after Pearl left?
And if he didn't want to leave.. and if cv's or anyone didn't have any problem with him, then why the hell did he left? I really lost hope that he will come back. Coz when he comes back, then nothing will make sense..(not in the show..) in real itself!
