In the serials I have been watching on rishtey, Thapki Pyar Ki, Uttaran, Swaragini. In these serials couples somehow end up marrying the wrong partner. Is this normal in india in real life. This happened in Thapki Pyar Ki when Thapki was not aware that she was marrying Bihan instead of "Druv Sir"and "Uttaran" Veer was not aware that he was marrying Tapasya instead of Ichha. Is this normal practice in India?
