So that way if I am the writer here, I will tie up loose ends and finish it. :-)
So basically what I would do is- make Aalu remember her childhood with some incident where Abhi protected her and I will have her repent and regret. She will help Abhi know about TaKhil. He will also know about the drama the team did and be mad for a few epis and finally be happy with Pragya. Pragya goes back to job and Abhi focusses on more music. Happily ever after!
