I strongly believe that this could be that twist. This twist will be the only explanation for Rk's behavior for everything he has done. If this comes out to be true than maybe he will realize later that in the process he fell in love with Madhu but then it will be too late. But then the part where he got shot does not make sense.
Just wondering if the story about his dad is fake too, and his mom. The worst that could happen is us finding that RK and Dipali are actually dating.
