Guys now I understood
Remember we got a BTS picture of a scene where abhi is spreading his open arms towards name AKSHARA written we will get this scene after abhi realises ak loves him
So after realising his akshu saved him and she loves him back ( this time he won't have doubts am sure - as he will see the bracelet in his shirt) and he will connect the dots and would understand that she has been faking it all this while for aarohi - it's not difficult to understand. When he will confront akshara that why she lied about not saving him she will start crying and share a moment of hug ( I guess on Christmas )
