Teju - He brings the same protection that Nandini brings to him. He is emotionally protecting her faith in things like hope. She is naive and the realities of the world do get to her , it's then Manik takes over her battles. Unlike Manik, Nandini doesn't have tangible baggage.
She comes from a sorted family, Rishab is getting well if Hospital sequence is to be believed . She is not worried about that. Her fears are about her loved ones leaving her and Manik is that eternal constant in her life. His presence is what she seeks most. He never lets her down. That Jeena Jeena sequence during Navya time- thats what Manik brings to her. Reality, protection and constant support.
Teju - friday the girl was overwhelmed already. The fear of concert and just she wasn't in a state to romance him. Simple .
@P - Relax. Meri Marzi confirmed he is staying. He also is not quitting the show. He is probably talking about the rumours of him doing other shoes post June or something . Relax.
