Bound by Obsession: A Dark Step-Brother Romance

My world is turned upside down when I suddenly become a step-sister to the son of a billionaire my mother is dating. From the moment I lay eyes on him, I'm struck by his stunning beauty, but it quickly becomes clear that he wants nothing to do with me. His savant syndrome, inflicted by his mother's abuse, only makes matters worse, and I can't help but feel like an outsider in his presence.

However, something inside me refuses to give up on him. I'm drawn to his intelligence, his wit, and his hidden vulnerability. Slowly but surely, I begin to coax him out of his shell, and before I know it, he's become completely and utterly obsessed with me.

At first, I'm flattered by his attention. But as his obsession intensifies, I begin to fear for my safety. His possessiveness knows no bounds, and he'll do anything to keep me close to him - even if it means hurting me in the process.

Years pass, and I think I've finally managed to escape him. But then, out of nowhere, he reappears in my life. And this time, he's not going to let me go.
