I know it kinda sounds stupid but they cant really show mukti dead and put an end to prem's love life. So I was thinking of different alternatives. One of them that came to my mind was heart transplant. Maybe some other girl who needs a heart gets mukti's heart and then she starts having feelings for prem kinda like the movie dil ne jisse apna kaha with salman and preety.
I know this sounds stupid but after watching todays episode i got a shock and maybe thats why these weird ideas are flowing in my brain.
