A big flaw?

I have been thinking a lot and i realized there are some big mistakes the CVs did...Ive been following the last couple of episodes with so much irritation so i might have missed a couple of points..so please correct me if im wrong ok?

The day physco drugged dakshu eveyone was at ayush's house right? and his real parents were there...and when ayush came to P zoo with his proposal to aku he came with fake parents...didnt any of the P zoo members notice this? that the ones who came to meet them and the ones who were at the pooja were different people...😕 and im kinda surprised that even Naina and Aku didnt notice this😲 because they already had doubts abt ayush's sudden change...especially aku...and according to my knowledge ayush's real parents dont know that he is getting married to aku yeah? didnt anyone even bring up the topic that day? i mean when families meet they talk abt the upcoming events and discuss abt these things right? its a marriage for god sakes!!!!!! if they had mentioned it ayush's parents would be confused as to what was happening yeah?

Am i wrong or did eveything go smoothly in that episode? please correct me if im wrong...
