See this is what it is
Abhimanyu knows about Kairav and Anisha and thinks her sister is Pagal
Kairav doesnt know about Anisha being Birla and was never serious with her
Anisha knows that Kairav is Goenka and she came to know her brother was dating Goenkas daughters through marriage fiasco/ media attention and decided to return
Simple right then why Abhimanyu thinks it's complicated because in all this Abhiras romance is gone 🤣🤣
