The new bajaj promo looked so funny because of how fake all the backdrop looked and him jumping from a building like that without proper safety. A different and more realistic promo would have made a better impact.
Anyways, anupre separation is inevitable and predictable, however if ekta knows what she is doing she won't show prerna falling in love with bajaj this time and keep prerna and anurag true to each other despite being separate, because ultimately despite KZK being about the kasauti of love for anupre, season 1 made it into a joke by showing prerna moving on with bajaj happily and only in last episode showing anupre's love for each other with bajaj being alone and mental. To keep the kasauti being real they need to keep anupre loving each other and nobody else despite whatever separation and misunderstandings happen between them otherwise it isn't much of a kasauti. KZK was always anupre's love story and how despite everything they couldn't be together.
