After the earthquake debacle when Shagun abandoned her children and Ishita saved them, the two kids let her know how much they detest her. Heartbroken and devastated Shagun handed over her kids to Ishita since she thought they will be much more happy with Ishita and the Bhalla family than they will ever be with her.
Currently, on the other side, Shagun is a changed person with a different zeal and attitude. She is serving for the betterment of women and children by running an NGO. She would have also worked with the police to catch some of the rackets exploiting women in Mumbai. And during one of those instances when she would have gone under-cover to expose an escort racket that she runs into Raman (Karan Patel).
Raman would have come to Mumbai for a business meeting when he gets one of the biggest shocks when he finds Shagun getting arrested being an lady escort. What he does not know is that she was under cover to expose them.
Yeh Hai Mohabbatein's upcoming episode will have Raman re-discovering Shagun as the new person she is now. Also, Ishita (Divyanka Tripathi) will decide to give Raman a surprise visit in Mumbai. Will she run into Raman with Shagun? Let's wait and watch.
