Well,I'm not sure.For me the show will never lose charm,until Mr.Ajju Punji is der,and ofcourse,the Arjuhi jodi.But maybe the storyline might lose it's charm.Every story sumwhere loses it's charm;apart from some shows ofcourse-and tht's very rare.No show has been able to top the popularity chart,throughtout,until,if it was short-lived.
It would definitely become latking and all,sumwhere in b/w,but it'll remain one of my fav.all-tym shows.
