Clothing: casual dark clothing

Origin: kylar never knew what it was like to be wanted. His parents died when he was young—a car crash, a house fire, maybe something worse. No one ever told him the full story, and no one ever cared to. He was shuffled between cold, indifferent foster homes, each one treating him like a burden rather than a child.

He learned quickly: Love was temporary. People left.

As a child, he tried to be normal, to make friends—but his quiet intensity, his unblinking stares, the way he always seemed a little too attached scared people away. The few who got close always left. He coped by keeping pieces of them—a button, a broken pencil, a single strand of hair. If he held onto these, maybe he could pretend they never really left.

By middle school, the other kids called him a freak. One boy pushed him too far. A week later, that boy was found in the woods, trembling, unable to explain what happened. kylar never spoke of it.

Now, in high school, he’s found someone new. Someone perfect. Someone who won’t leave—because this time, kylar won’t let them.
