Kanya's family has two days to vacate their home. Rabir has two days, and then he must get married. Ayaan has two days until Guru kills him.
I think, to save Ayaan, Ranbir is going to black Kanya. He'll tell her that if she marries him, he'll let her family stay in their home. Naturally, after some cajoling (like all ekta heroines), Kanya will sacrifice herself for her family. Ranya and Shanayaan will get married.
