Why same Vilians/vamps enters? nothing new?

This is the question I want to ask Cv's as why same negative charaters enters in Geet all the time?😕 ...though I m actually loving😉 all restart of lovestory n romance😃 as its fun seeing angry young maan but I hate Naintaara😡 n not so excited🤢 to see her again,as why cv's always gets same characters enterring n leaving😊 than again enterring😕 n so on🥱 nothing new🤢 to bring exciting to the show like first it was brij😡,Naintaara😡 than Naintaara's brother Arjun so same story we know their story😛. Sorry but look to PKYEK Show they always get new negative characters to bing excitement n suspence in the show😲.This encourages viewers to get hooked to the show as they want to know abt it n wats their story.I think its now time Geet cv's also get new negative characters to create suspense n thrill in the show! Like get a hot new Guy as Maan's Rival/Business Rival in the show!😊
