Actors have a habit of exaggerating. Some exxagerate the success of their shows and some, the importance of their role.
That being said there's no doubt that kzk has been a successful show given the noise surrounding it even today. Moreover PHs across the board are coming up with sequels and reboots of their own popular shows, showing how successful this format truly was.
I wish, truly wish that Ekta had given up on her insistence on somehow fitting in Bajaj fter his first stint flopped. Had she not brought him back and had parth's illness not put him out of commission, this show mightve definitely completeted its intended run till December. But even that is doubtful since parth wanted to quit and I doubt he'd have obliged to stick around post November. So there's no doubt that the show is ending a month before plan and I don't blame the channel one bit for losing patience given what happened in the 3 weeks of parth's absence.
In any case since Media articles and entertainment portals are God's own words,
SURELY all portals calling kzk a successful show proves that it is indeed a success. 😁
