This gen of KKB is heavily focused on the ML. I think even Raunak had more to do (and he still has a character graph, monologues, long dialogues with supporting characters to establish his pov). Shiv obviously has good dialogues, monologues and his scenes are written with care. With both guys, an attempt is made to show them as real people, with emotions, flaws, biases, wrong decisions, etc. While the FL Prarthana is a cardboard cutout. Whatever she does is typical FL things, there is zero twist or some unique character trait that makes Prarthana...Prarthana. The writers don't care about her, at all. How easily she believed Raunak that Payal was the mastermind. And of course, there are her stupid, preachy dialogues.
Even Smita, Bua Maa, Tanya, and freaking Sonalika get more scenes explaining their pov.
If they want it to get better ratings, they need to focus on Prarthana and give her a good script.
