Sanchi may act cool and just go to her room silently. Trying to take her life or talking to her best friend. First she may try to hang but then develop cold feet. search for phenol or slash the wrist with a broken bottle. Meanwhile Jagya and Shiv may crash the door and save her. Jagya may feel guilty, say sorry and accept her with a glowering Ira looking at him.
Second option. Sanchi may shout at Jagya, take ganga's name and let everyone know that Jagya is having an affair with ganga. This will make Jagya very angry and he may just walkout never to return.
Third option. An angry Ira will start questioning Jagya saying that when she asked why did he say yes. Ira may further say that anandi is also not suitable for Shiv in her eyes and yet they have accepted her gracefully. And Ira may say that if he goes by this decision, she will not allow any relationship between the 2 families in future.
Fourth option. Alok, Chotima, Shiv may try to drill some sense into Ira saying that it is better to break the engagement than suffer long term consequences. Ira may not listen at first and she maybe convinced after more pursuation. Then sanchi will have no say.
Fifth option. Sanchi may try to separate anandi and Shiv, anandi and Ira and make life difficult for anandi in particular.
Or the CVs may cookup a surprise like pulling a rabbit out of a hat.😆
