Well now they story is tricky.
I dont know what exactly will happen and its tough to guess..U never know what might happen at the last moment.
well my first prediction is that nihaal will get engaged to megha and on the wedding day there will be something(maybe nihaal disinterest)that will make megha realize that he loves someone else.or maybe she will hear them both speak.so megha unites nihaal and suhana.
it might also happen that when suhana confesses her love for nihaal..vishu returns back home saying how much he loves suhana😕😕
or nihaal megha might get married...suhana realizes later how much she loves him when nihaal tries to make her jealous.
but i just want the first situation to come true.and i dont want that hideous vishu to return
