As you know all of them right!

Let me introduce

From right first couple rudra and bhavya
Than in middle shivay and Anika
Than at last omkara and gauri

And as you know full oberoi family
Than I don't need to do lots of work

As the story starts one day before rikara anniversary (omkara and gauri)

A new character is also there
He is also a part of story
He is cousin brother of oberoi family
Rishi singh oberoi
Dadi's brother's grandson
And
Shivomru is familiar with him
