I slightly disagree with you here. As per my observation from past few episodes , i have seen sharu is aware about something abnormal happenings around her.
Whenever vyom is closed to her. Or whenever he almost get success in getting her attention and getting her believe on his story the ghost appears and spoils their moments.
I feel namik appearance is only related to vyom closenes to sharu.
Even she realized it. One more thing , one can also make rhat sharu instantly pushes. Vyom away as soon as she feels namik close to her (although its just a presence and few light effect )
I think when he said last episode that a man who loves a woman more than a life when turns hatred , life is in danger.
Its a huge sign here.
He is not hurting her. But trying to hint her on something.
Vyom did not know whether the flower shop ever existed near his and sharu college. Why i feel? Namik used to work there.
If he had killed namik or even have met him. He must know the shop and its owner.
Vyom is lying. But he is not the killer.
Sharu memories have lots of secret and she is not clean but not a villain
Namik is hinting at something constantly. Lets see who cracks it.
And vyom father...he is extra good...and when things are extra good they are suspicious.
Hereby...i rest my case.
