How could you say that. Akshara entire life revolve around naitik and singhania. Same with naira. Same with akshu . Same with abhira .
Yeh show shaadi pe based hai. Couples hote hai. Remember jab abhira Arman ki shaadi huyi thi toh purane 3 legacy couples dikhaye gye the.
Yeh notion meko false lagta hai ki it is only female as legacy . It is the couple only that define legacy in rishta world
I am not saying they aren’t important for story that’s why I said they are plot devices they are a major part of female lead’s life but they don’t matter much for legacy. Like when they show FL entry they only show oj Akshara’s blood line Arohi and Ruhi never got introduced in the same way. Also only in gen 2 the previous ML used to be mentioned in gen 3 it was always Naira’s dress and jewellery being mentioned by Akshu ams Arohi and in gen 4 Akshu gets mentioned more than Abhinav and Abhimanyu. They don’t even show the ML families like there is no mention of Birlas

Well if he does return it’ll add a twist to FL and step dad angle and Birlas can return. Abhira will be Arman Part 2 as everyone in Birlas is related kids but Abhira will be not Abhimanyu’s blood daughter
Ruhi isn’t choti ruhi, Abhir seems to randomly pop up for trp sake and could very well be just Rudra who was like some frnd of Abhir before he died decided to avenge for his death.., what even left of Akshara and Naitik here!
