Okay.
So maybe Shiva realises Suman Kaki & Mami's plan at the last minute, and swaps the groom's place. Raavi learns of it all and accuses Shiva and hates him. Then Shiva runs behind Raavi trying to pataao her, but Raavi sakht laundi banegi, and won't melt.
Shiva will keep climbing the marriage, but Raavi will keep saying there is no rishta. 😎
Then Raavi will apply for divorce and Shiva will accidentally sign it and the cycle continues. Is that what you are trying to say? 🤣
