Hey!
I have a feeling that if Aroonaji will enter DSK, this is my take on how.
Take 1: Anu will try to get out of Chetus life but then Aroonaji will come there and bring Anu into some senses and tell her to fight for her right and then Aroonaji will help Anu.
Take 2: Anu despite knowing the truth about Aditi trying to ruin Chetus life, she will try to expose Aditi but then, Chetu will kick Anu out of the house thinking that she is lying and that is when Arooonaji will support Anu and give her power and support to expose Aditi.
Well, what do u think?
