Raised in the shadow of darkness, Y/N L/N and Mattheo Riddle have spent their entire lives side by side — best friends bound together by bloodlines, secrets, and a world that was never meant to be kind. But the summer before seventh year changes everything. As war creeps closer and their fathers prepare to brand them with the Dark Mark, the line between loyalty and fear begins to blur. Back at Hogwarts, whispers follow them through the halls, friendships are tested, and the future waiting for them feels darker than ever before. And somewhere between late-night conversations, lingering glances, and the quiet terror of becoming monsters, Y/N and Mattheo begin to realize that losing each other might be the one thing they can’t survive. In a world built on power, destiny, and violence… what happens when two people raised in darkness start wanting something more?
