Ekta please go ahead and kill heer and prem together in an accident or any way. You are good enough to come up with 1001 plans to kill people. On a side note, you can write a book on this subject. Anyways, coming back to point, you can then cast both Harshad and Aditi in your new show. The new show's trps will touch the sky.
And in KDMHMD, you can focus on Preet-Ash and Harman-Meher-Maya love stories. And Preet can come ahead as responsible son of family and can work on imporing Rishab Rampal after he has married Veera. Nihal can find a better girl and get settled somehwwhere.
After a year or so, you will be ready to kill them in your new show, I assume, as killing main leads is a must in all your shows. By then, KDMHMD will be all set to take a leap.
Them our Harshad can return as Preet's son and Aditi as Nihaal's daugher and they can finally reunite to complete their eternal love.
Friends, sounds like a piece of junk!!! But believe me, I could not think any thing more ekta..ish than this. This is the only crap she shows all the time. So I have this solution so that we may get saved from seeing Heer with anyone else. I wont be abe to take that at all.
Please dont get upset with me for giving this silly suggestion to that crazy lady. I am just too depressed right now.
