I too believe that Vikram did the accident and they Ranisa-Veer-Rhamadeer are covering for him
Vikram was either too drink that he didn't remember or Ranisa blackmailed him to not to confess.
That is may be why he is softer towards Rani. And after the marriage became protective too. He is guilty.
Pre or post marriage their encounter is plotonic. Their will be too much craziness in their relationship, no balance.
But if Veer gets jealous, I don't mind 🤣
I have a feeling Vikram doesn't actually remember that he did the accident, if he actually did it.
