My theory:
I have a different pov,I feel new person is to instill insecurities in male lead and Malini to fill amle lead ka head with thought that imlie never loved him,she was just fulfilling her duty as she was married to him,now when she left him she is moving on,as she never got choice to select her partner.
Ye moti buddhi manega bhi🤣
I am expecting lowest level in which they can move to male lead to😎
