I think it’s because people are under the impression that the show will just repeat the storyline of the previous season so maybe they think it’s pointless. Or perhaps Mohit Sehgal is not that well received as the promoted Male Lead.
They should try to clarify who the actual Male lead is if that is the case or give better promos at least not the vague ones.
Moreover, even if they try a different story this time, will it actually appeal to the masses is the question.
