What if AK was all alone?

The first time she left home, he didn’t know one of the twins was alive. Only after meeting Abhinav and she fainted. My question is what if none of the twins survived. Would Abhinav still followed her and help her around and would she live-in with him? 🤔

or now what if she wasn’t pregnant with Abhira and both Abhir and Abhimanyu died. Would they show her living by herself independently and finding a new person 😂
