Be patient dear...we can obviously expect various plots and subplots in a show.I'm sure all these will have a huge impact on anirudh in the future when he comes to know of the real mini.Now at present he doesn't have any reason to hate her since he believes he was the one who cheated her by promising to marry her.But in this process slowly the real mini would be revealed in front of him and that would be the trigger point for him to rethink of her.
If ani-mini were the end point then they would not have shown mini this black which according to me shows that slowly but steadily the makers are laying the foundation for Rudhita in future.....just remember the title song lyrics---mil jayenge saanj aur sawera jaise😊
