Just one thing though, if people are having issues with Ishita giving priority to Ruhi only because others in the forum have an issue with Raman giving priority to Adi then you're not really having a fair perspective. Judge the show for what it is not for what 'Raman/Ishita haters' say.
Adi should be Raman's first priority, why not? So should Ruhi but I think the difference is that Raman has given in to unfair demands from Adi, where as Ishita doesn't bend the rules so Ruhi can get her way. I'm not blaming Raman here because he just wants to be with his son so he will do anything for that time with him. I feel for Adi too because he's been manipulated his entire life but Raman himself doesn't know how to deal with the problem. Raman isn't sure of his own parenting so how can anyone here blindly justify all his actions?
But you also can't deny or fight that there will be more highlight on Ishita and Ruhi's bond than Adi and Raman. The show began with their relationship, everything else came later. If it suddenly came out of the blue I would understand the annoyance from people but it hasn't.
