The marriage will take place but the question is what will happen when Vansh knows the truth. A portal reported that truth will be out to Vansh before he ties the knot with Ichcha. However, that"s far from being the truth.
On condition of anonymity, an actor says, “If Vansh came to know about the truth before then Tapasya will be unmasked. If this were to happen, he will invariably not marry Ichcha. The letter which Ichcha had written to Vansh about her past with Veer will be out only after the marriage."
To know how things pan out, keep watching Uttaran.
