Surprised to hear this, yes I am right. And the reason is -
Had prashant not left Aarti for another woman, she'd be living a miserable life with him. He'd have kept on tourchring her. Because P left her, Aarti found such a wonderful, loving and caring husband who understands her so much better than P could have ever. And a much better family than the dubey's. Ansh got wonderful father who is his superman. Both Aarti and Ansh found Yash, who is willing to do anything for their happiness.
And now because of P's simple question in Fridays epi. Yash is left wondering. He will now start to reevaluate his feelings for Aarti and will confess his love( as per the spoilers) .
And all this happened because PRASHANT LEFT AARTI. So I think Yashji, Aartiji, the entire schindhiya family and all of us should thank P for leaving Aarti and Ansh.š
