Today Angad called Sahiba meri biwi ...
Secondly I noticed in vaada seq of seerat and angad that, there was a hesitation and surprise when seerat ask for promise.he find it weird that why she is asking his support, if anyone has seen the og, Riddhi took responsibility of Dyuti as well which was really weird and he supported her too. However, the leads got better.
In my observations, Angad is actually right in his decision, the thing is he knows Seerat doesn't love him but Garry. Garry has done enough to ruin his reputation and now he is starting a fresh life with sahiba. Today the way he wanted her to understand him and him using Humara and Us shows that he has move on.
Even in og, the purpose of this marriage was to protect dyuti honour because his brother took it. For those who are saying seerat is not saint, she is definitely not. Precap is the big example but she and garry have left no choice. In order to move on Angad or Riddhi took this decision.
