Because of the engagement fiasco...yes its real, no its nakli, Zoya will not believe Asad so easily. I don't think any planned out confession is going to happen. Its going to be more like a life/death incident, where he lets it all out. In a panic, forever reason, is the way I see it happening. Even than she might doubt him...but atleast there's a chance that he means it. Why would she not doubt him? Even now, he starts by saying they are opposites, how unromantic is that!
Try this: Maybe, buy her a saree, and have her wear that, get a pizza, and chocolate cake, and don't forget the diet coke, and maybe some pakoras (bhaang preferred) and play the song from the pakora night. This would definitely convince her!!đ What do you guys think, isn't this a nice option??
