@RameshParab Akshara has already died in the timeline of the story ... Ruhi does not completely hate her, she still wishes to hear explanation from her but yes she dislikes her. As for Abhira, she will have some appearance in future updates as a member of Poddar family. Ruhi won't particularly hate her but since her relationship with the entire Poddar family is constrained, she wouldn't have much to do with Abhira too.
About Birla siblings hating Abhira, no they don't.
As for Akshara, shivansh and Ruhi both do blame her for the past but none of them blindly hate her.
