It's the first time you have a made a topic haven't you Rush😊
I believe CVs have planted something big for Kunal and finally are concentrating on his professional track in a big way (At least I hope so😊). As you said Hospital bill is just an excuse to take KC's career further, a successful one.
I think his Maqsad might be Abhay's barbadi (I so want this to be his maqsad). I hope this case is something related to bringing Abhay down professionally and that is what KC is referring to as his Maqsad.
I don't think it will be Thakral or Richa as they wouldn't end Richa's character any time soon as she brings in good TRP. If I am correct, the last time Parichay had high TRP of 2.7, it was after Richa asking Kunal to fill her maang promo. Richa's nautanki has always brought good TRP (May be elder generation loves her nautanki, the ones who contribute heavily to TRP). So it has to be Abahy in my opinion.
Lets wait and watch, hope our wishes to see a successful Kunal finally get fulfilled
