I dont know why people are so cribbing seeing the scenes of Akshita doesnt it go so well with their characterisation, Ishita is desperate for Akaashs attention and love seeing the love and mutual respect, understanding that she sees between Aarya and having been the rejected one by Yashs shes the wounded tiger out to do anything to get her man by hook or crook and so the desperate measures to seduce him. And obviously it would be dirty as shes desperate.
Coming to Aarya dynamics they are still recovering from big shocks how do you expect them to romance right now and feel all goody goody instantly. Aarti did comfort Yash passionately when the truth got known.
The dynamics , circumstances with which the two couples are bound with each other are different and to expect same kind of scenes/ romance between both the couples would be sheer stupidity. While Akshita dont have past baggages of relationships they are fresh AArya had it and were more mature as individuals with children to expect the same in both would look idiotic and cheap . Both are different and I applaud the CVs for showing them differently.
and about Parallel tracks they are needed for long term sustenance of a show and would help the main leads take some rest too.
