I belive the thing that leads to decrease in trp, isn't story after the leap, it is the leap itself. People were highly disappointed over two recent leaps. even me as a simple viewer was sure that these leaps are deadly for TPK and along with other fans i request CVs to change their decision but as we all know they never listen. they could show lots of good tracks after kabir track and seriously i still can't understand why they showed the 7-year leap!!! Even it wasn't enough for them and they took another 15-year leap and alongside of killing Bihaan they killed they own show too. TPK have already lost two third of their audience during these two leaps (trp reduce from 1.5 during vani track to 0.5 in current track) out of frustration. No matter what they show now (thayaan, niyaan, bimar, timar,...) it doesn't change the fact that Thapki was seperated from Bihaan for 24 years and from Bani for 15 years and the fact that she was miserable in her whole life (except a few month that CVs didn't even bother to show it). no matter how much they show romantic scenes between Thapki and aryaan now, it dosen't satisfy me at all cause i didn't get this when i wished for (it's like a cold soup that i don't enjoy eating). I think the current track has no potential and it just getting worst day by day, hence arguing over pairing is a waste of time cause the problem isn't new actors or new pairing, the actual problem is the leap itself.
A solution: Some people ask for a reincarnation, i suggest an easier way: They can show all of this was just a dream of Thapki while she was in a coma (for a couple of month) after her accident and continue the story from there but this time without Vani, Kabir and stupid Sankar. l don't have any problem with Kosi and Shardha, they can stay in PN and make as much as troubles they want for thahaan.
