Infact you got my 2nd and 3rd question and not the 1st one...😊
1st Q: CV knows his daughter is in love with Ashu and since his time is coming to an end, wanted to marry Nidhi to Ashu. That is clear. When BB and DB are concerned, did they know why CV wants to meet Ashu and what he is going to ask him?If they do not know, they will not tell Ashu not to say No to whatever CV asks them. So, they must have discussed with CV before and have a fair idea, what CV is going to ask Ashu..and they also want Ashu to marry Nidhi...
