Before the leap both Naitik (Karan Mehra) and Akshara (Hina Khan) were shown meeting with an accident. Though Akshara only had minor injuries, Naitik was hurt badly and he slipped into a state of comma. Ever since then Akshara has been managing both business and family.
However, the good piece of news is that the upcoming episodes will see some smiles on the face of the family. As per sources, the entire family is gearing up for his birthday of Naksh (Shivansh Kotia). Soon, there will be a birthday party for Naksh and to his surprise, Naitik will regain consciousness on the same day and try to understand things.
This will bring a ray of hope to the family members and also Varsha (Pooja Joshi) and Ananaya will contribute a lot for Naksh's birthday.
Pooja Joshi confirmed the news saying, "We are all planning for something big and the upcoming episodes will be very interesting. However I cannot divulge anything as of now."
