I don't think there will be a leap of 7 years. If they do it, they will have to progression in each character's life besides Dev and Sona.
- Neha's second marriage
- Ria and Nikki's marriage and post marriage families
- Saurabh's wedding and his wife
- Kids of Elena and Vicky
And I am pretty sure looking at the budget of Gareeb PH, they can afford to bring in so many new characters🤣
