My reasons for saying that are -
First of all this phase is when shivika arr growing in their relationship and have trust on each other.shivay won't behave in a nonsensical manner without any reason on anika as she is now his support system.sonhe has a reason for this
Second is actually the ms promo where anika is going to tell Shivani about his real mom so that also is yet to happen
Thirdly in lee's live chat on ig Siraj Mustafa said that we viewers would get to see a lot of twists and turns with revelations so that is also about to happen.
Lastly the biggest reason is Nakul himself.he said in his interview with raj baddhan that shivika are on the threshold of accepting each other and that lots of romance is coming up.
So friends don't worry,as we all know our shivika are very actors and they bring out everyone's truth by acting this way or other. No pinky , tia or anyone else can separate them.
