Kahiin to hoga is going to an end. I think the ending will be like this:
Kashish and Sujal get married and live happily.
Varun will leave shivangi and go back to Mehak as she is all alone and he will feel sad.
Shivangi will leave Varun and tell him to go back to mehak as she is pregnant with his child and she needs him.
Swayam and Alisha will be jailed as Abhi has all the proof.
Sneha will be alright as Abhi will have the money to pay for the medicine.
Abhi's wife will come back and live happily with them.
Abhi's family may be will live in garewals home.
Hope the ending will be like that as mentioned above!!
