Wanted to post ths when vikram name came up- I think humeria is the master mind here. The whole plan is hers and she is executing it beautifully. She knows that ayan is forced to marry her by razia and she knew her mothers motive behind sending her away. So she played a bigger game to let the person she loves free. The bus accident, rajni shukla, and now vikram are all a part of her plan. It is her way of going out of ayans life and correcting all the wrong her mom made on ayan.
Now Ayan will realize the importance of the person he has always taken for granted. The love he couldnt see will be out with jealousy and to keep a close eye on vikram, vikram and humeira will stay with them
