Abhira reunion at this point does not make sense to me. AbhiM needs a solid redemption track for Akshara to fully trust and accept him again. Their best bet is to go ahead with Navra for now and show Akshara completely fall in love with AbhiN. Later when everything is going well for Akshara, they can have AbhiN exit the show to shake her world and bring back AbhiM in her life.
Maybe add Navra’s child to take the story forward too. I think this is the only way that both Navra and Abhira fans’ wishes can be granted. Pehle Navra fans ko khush karo phir Abhira fans ki baari. IMO She shouldn’t just go back to him only because she loves him and the great manjari thinks they are meant for each other.
