If you refresh your minds, it is Antara who let goes of Raghu's hand, it is Antara who is first walking away from Raghu on that bridge scene, it is Antara who walks away from the bench scene, it is antara who is taking her duputta away and it is Raghu who is left behind with tears, get angry, beats up other people, and is lashing out.
This is evident that Antara will get fed half-truths about her father being killed. Aman hinted yesterday to DM, that Raghu and Antara talk about kashmir and one day Raghu will be the one who will say he gave a parcel. Antara will put two and two together, and will mistakenly believe it was Raghu. Raghu, shaken by that discovery, tries to find Aman...and the story will unfold there.
