Hindi TV Serial - Iss Pyaar Ko Kya Naam Doon - Relationship between Arnav and Khushi

The story went down on an angle. For the last 6 months, things have been that there is a marriage between Arnav and Khushi, but the whole angle has changed. The marriage that they had did not involve any pheras and this was now known to the family, and hence there was the concept that the marriage needs to happen again.
Now, Dadi is not very friendly towards Khushi and hence, when there came the question about the pheras not yet happening and this marriage needing to happen again formally, Dadi made her way to Khushi's house and there started bad-mouthing them. She spoke badly to them, made the inference that Khushi was after Arnav because he was a rich guy and she was after rich people.
At the end of this discussion, Dadi finally got what she wanted, with the relationship apparently broken, and then Dadi came back to the house and told everybody that the relationship was now broken. When Arnav heard this, he was very angry and claimed that he will make things better and also told Dadi in effect that this relationship will happen and she should not try to block it.
However, there is something hidden in the relationship between Dadi and Garima which can be problematic.
