The show started with RM and his mom come to Ganga's house and agree for marriage in front of everyone
Later on in the show Ganga is crying in her room and thinking about SA-Kaveri marriage( it has happened)
and than they show a flashback of Ganga and RM conversation where Ganga agrees to Marry RM
AS far as i saw the video it was not a dream
I am quitting this show from now
