Yeh Hai Mohabbateinhad Romi and the rest of his family coming to know about the son he has had with Sarika. They get to know she has placed the baby for adoption and by the time they decide to take the baby for themselves, the child would have got adopted already. Chances are that Ashok might have adopted the baby.
After Romi refused to take responsibility of his baby with Sarika, she delivers the baby only to name him Rohit Bhalla and place him on adoption. Ashok, who knew about this before Raman (Karan Patel), Ishita (Divyanka Tripathi) or even Romi, gets to the orphanage before them to adopt the baby himself.
Everyone knows Ashok has nothing to do with the baby and he just wants to adopt Romi's only possible child to probably blackmail Raman. But by the time they figure out if they wanted the baby or not and decide to adopt the baby, Ashok most probably has beat them to it by adopting the child himself.
Sarika, on the other hand, still does not want to do anything with Romi or his child. Though it is unsettling that she has placed her baby for adoption since she did not want to abort the child previously, it is yet to be seen what her real intentions are.
