I remember some comments saying,they're showing more of Reyansh's jealousy about Pranati and Archit and other stuff more and Jugnu has been sidelined.
However,Jugnu's character has always been pivotal for twists and turns in Prayansh's lives till date.
From reuniting after all these years to custody battle to Pranati staying in Khurana house- everything that happens with these two main characters of the show somehow revolves around Jugnu,with or without directly in the picture.
Remember when Reyansh went all psycho and started misbehaving with Pranati to get her out of the house during Armaan's wedding? Everything changed when Jugnu goes kidnapped. In fact, even though Reyansh still remains a jerk he realised a couple of things including his love and concern for Jugnu and what he did to Pranati all those years ago was wrong.
Har plot twist ye Jugnu le kar aati hai.
So,she is not a main character but the central character of this show.
And I sincerely hope it stays that way.
