The CVs have totally dropped the ball when it comes to Keerti as a character.
Up until the point when the family finds out the truth about Aditya and their subsequent separation, I understood her actions. She had grown up with the very conservative Dadi and I understood why she didn't speak up. After all the torture she went through, it would take time to pick up all the pieces and feel whole again. Her spirit was broken. And the CVs had an excellent opportunity to show how she gradually comes into her own despite everything she suffered, with her family standing firmly behind her at every step. But they didn't offer her character that chance at all.
The first instance that comes to mind is the sequence where Kaira take her out with them. They are going to a couple's party where she is denied entry and she chooses to go home without informing them. I am not going to debate who was right or wrong in that situation. It was discussed extensively on this forum. In my opinion, that whole track was poorly done. Instead of showing something positive where she finally gets a chance to smile and relax, they unnecessarily turned her character into a plot device to create needless conflict between Naira and Dadi.
Where she should have been entirely wary of new relationships after her history, she was shown to fall in love in seconds. Her friendship with Naksh was honestly sweet. They should have let that friendship grow. He should have been there for her as friend and that's it.
Instead they again used her as a plot device to create conflict between Naira and Dadi, where Dadi manipulates Naira into considering Naksh as a potential groom, putting her in an impossible situation. Which then led to the rushed wedding with Naksh's unwarranted "sacrifice" and eventually a major misunderstanding between Kaira.
Even today, her being caught by goons was completely redundant. She again had to "saved" by Naksh and Kaira. It should have been a powerful moment for her character where she is actually given a choice of her own for the first time in a long time.
Character roles can be very well fleshed out too. They can be three dimensional roles with interesting stories. They don't always need to be reduced to mere plot devices. It's a pity because she could have been an interesting, mature character but they chose to reduce her to a perennial damsel in distress.
Just FYI, this whole post is directed towards CVs. I have nothing against Mohena. These are just my opinions. Feel free to agree or disagree.
