hey Great SwaRon writers pay attention please

Swaron writers I am manisha nd a newbie on the forum. And ofcrse reader of your fantastic os/ss/ff's.
Actually I have a concept in my mind correction in my heart. I just wish if anyone could write a ss on it.
Here it is-
After many hurdls Swaron in open relationship.
Really happy.
But there is a Khalnayak you know Shivam. He jst wanna take revenge from swayam as he want sharon back in his life .
In ds context he try to kill swayam.
Will swaron survive or shivam win in ds bloody battle?

I am a very bad writer so please someone write down on ds concept.

Hoping for positive replies
