For example:
GHSP: Geet did not showup on her engagement day with Maan. After knowing the truth that Dev(her ex husband who cheated on Geet for money and made her pregnant with his baby) is Maan 's younger brother. So their engagement was cancelled.
IPKKND: 1. On Akash & Payal's wedding day, Arnav misunderstands that khushi and Shyam (Arnav's brother in law) are having an affair . So Arnav did not confess this love for Khushi. and he disappears during the wedding. Then he comes back and forces Khushi to do a 6 month contract marriage with him.
2. The second time when both Arnav and Khushi decides to marry each other. Arnav finds out the bitter truth about his past. In which Khushi's non biological mother/aunt was the other woman in his dad's life, due to which, Arnav's mom had committed suicide. After knowing this bitter truth, Arnav doesn't show up to the wedding altar on time. While Khushi waited for Arnav like a madly in love bride.
Predictions for on ASYA 's nikah in QH:
1. Tanveer's truth to come out in front of the Khan family, along with the truth about Zoya's real father.
2. Tanveer might create misunderstanding about Zoya's father being alive, By bringing this up infront of Zoya. Thus it could lead Zoya to misunderstand Asad. Then she might disappear without telling anyone. And Tanveer might use the chance to create misunderstanding for Asad. By saying that Zoya left the nikah because, she didn't want to marry him or she was confused. Similarly, like what happened on their Asya's fake engagement day.
3. Asad might not show up, after knowing that Siddique is Zoya 's real father. He might be confused and not know whether he should marrying Zoya is the right thing or not. But he will still marry her, because he loves and cares about her.
I find Asad is a combination of Maan from(GHSP) and Arnav(IPKKND). Zoya on the other hand is also a mixture of Geet and Khushi.
All I can say is that either Asad/Zoya might not show up before or during their nikah. But I really hope my instincts prove me wrong. since 4 Lions wedding sequences are always unpredictble.. Whether it was Geet, IPKKND, and now QH.
