If him saying she would bring happiness to Sujata's home is an indication..it has to mean Atharv n Vividha come together na? Why a bitter future?
Anyway I think he just said it wrt his illness and the fact that they are'nt exactly living as a family as of now..
Yes, but at first he said that she would bring happiness to his own house then he changed the matter...
Though I am not sure if it is a hint or not...because dialogues could be misleading too...
