She married him knowing one thing clearly: love was never part of the agreement. Their marriage was built on terms, not promises. A shared home. A shared bed. A public image to maintain. Nothing more. He was distant, controlled, and never cruel — but never warm either. To him, she was a wife in name, a solution to a problem, a role that needed to be filled. What neither of them expected was how silence could become dangerous. How intimacy without love could still leave marks. How wanting someone could come long before admitting it. As the line between obligation and desire begins to blur, she must decide how long she can stay where she isn’t truly chosen — and he must face the truth he never planned for. Because sometimes, the most dangerous thing isn’t loving someone too much… It’s realizing you never meant to love them at all.

"You were never her, Aria. You were just... there." Jason's words echo in my head as I stand in the back of the church, watching him mourn another woman on her sister's wedding day. Isabelle. The perfect dead girlfriend. The ghost I've been competing with for three years. I thought I could be enough. I thought love could grow where grief once lived. But when I find the evidence, when I see the hotel receipts, the text messages, the photos of Jason with Isabelle's sister Violet, I realize the truth. I was never the love story. I was the intermission. What I don't know yet is that nothing about my marriage was real. Not Jason's cruelty. Not Violet's affair. Not the stranger's rescue. They've all been playing a game, and I'm the prize they're willing to destroy each other for. When the truth comes out, when I discover why Isabelle really died and who's been pulling the strings, I'll have to decide: Do I let them destroy me, or do I burn their whole world down?
