Ok, this has been bugging me, if Shyam was having an affair with any other RANDOM girl, would ASR have married ANYONE? No, ASR would have never married anyone else. He probably got rid of whoever that 'girl' was. He only married Khushi because he loves her and in addition to protect his sister, he is also protecting the LOVE of his life from that snake. For example, "the holi color scene". I hope Arnav realizes that ASAP that he loves Khushi and tries to fix all the mess created by ASR.
