Let's Guess

My Version .. So let's Have the Original Names Retained and Shivani be Shivani itself .

So Shiv n Shivani are Siblings .. No idea on how Rajan Bedi and Madhvi will be still related to Vyom .. I can't even imagine how it travels

None of them remember their pasts .. Except RajVi

So Vyom 2 is in love with Shivani .. Shiv is the rich Rockstar ... I seriously doubt that this time also Vyom only will be Negative ..Cos that's how a story should proceed and since all the Spoilers point towards Donal paired with Namik

Shiv gets flashes of his past . (the sketch of Donal)

And mostly Vyom faking his love for Shivani .. To get revenge from Shiv for killing him

Everything goes smooth till Sharanya's entry ..They LL remember their pasts in Kapali Hills as usual .. Except who killed them.. Only Climax LL give them memories on who cheated them

I somehow feel Shivani is not doing a full fledged role as Donal is still in d story.. Mostly Revenge Track
