Yeh Hai Mohabbatein 20th September written episode: Ishita (Divyanka Tripathi) has finally realised she has fallen in love with Raman (Karan Patel). She witnesses how much he has changed and how caring and pure hearted he is that she finally forgets he is Ruhi's father or Shagun's husband and accepts that he is her Raman.
On the show, Shagun taunts Ishita calling her a fool and thanks Sanjana for her cooperation. She promises to produce Sanjana’s play in return. Mihir bursts on Shagun and is about to throw her out of the hall. Purnima comes and stops Mihir. It is revealed that cook Purnima Prakash is none other than the mother of Shagun and Mihir!
Toshi confronts Purnima, who says that she has the right to meet Ruhi as her maternal grandmother. Mihir slams both Purnima and Shagun for their greedy and ambitious nature and he refuses keeping any relationship with them.
The Iyers hastily leave the hall. Ishita goes to talk with them and tells Raman to be with Mihir. Shagun tells Mihir that she has stopped his marriage so that he rebuilds the relationship with her and comes to her marriage.
Shagun mentions that Suraj has come to know about the split between the siblings and has challenged her to bring her brother to talk about marriage. Mihir completely loses his cool and says that he can never go to arrange her marriage with Ashok. He expels both the women.
Raman comes to the Iyer house with the fear that they will be upset with the alliance. But surprisingly The Iyers say that they are proud of Mihir, who can even reject his own family, for ethics and principle. They decide to complete the Tilak function.
Ishita comes to Mihir and tells him that time has come to forgive Shagun. Raman has moved on in his life. Now Mihir should forget old issues and repair his relationship with his family.
After Ishita leaves, Raman comes to Mihir and supports Ishita’s opinion. He says that when he has moved on in life and has got married again, Shagun should get married and start her new family. He tells Mihir to stop being stubborn. Ishita comes back and hears Raman’s words. She feels happy.
