Yes it happens like this only, even in Yrkkh both younger Naksh and Kairav had significant role but once the show took gen leap, they were made only props and the story completely shifted to the daughters, who appeared only as babies.
In Ph's other show CS also they did the same, both the boys had good SS but after leap, Leads' daughter became the main Lead, played by the same actress.
The only show, I remember where story centered around Male offspring was Ishqbaaz, where Nakul played the role of Shivika's son, but unfortunately it was big flop and they've to wrap the show in one month.
I'm guessing Ghum going the same way, they're introducing the Girl child, only for this reason, to secure the plot and character for a Generation leap.
Obvio. ITV runs on that only. Gul was biased towards Nakul that's why it happened! SC was way popular than Nakul. I liked Annika so much.
