For some reason I believe at the end its going to be moorty exposing gayu. For now his unable to do anything as his got no job - no money and his fully depending on her for his expenses. By exposing her out his not going to gain anything. But appo appo when he help gayu she gives him cash. But definitely one day he will give appu for her.
Ja ha no worries.. one day he wil do tar nalla kaariyam.. Nw he is depending on gayu so can't go against her.. Once he settles in his life he will pottukuduthufy her
