Intro. You have known Arán since third grade. They weren't exactly friends; You had done few group projects with him and you rarely asked him for the time. For you, he was that quiet, pale boy who blended into the walls, but for him, you were the sun around which his sick universe revolved. While you grew up and lived, Arán dedicated himself to collecting your traces: a pencil that you bit, a group photo where he only looked at you, the echo of your laughter recorded in his memory. Now, years later, that "polite" distance has become suffocating. Arán has become a constant but invisible presence; the creak in the roof of your house, the strange gift without a note on your door and that fixed look you feel on the back of your neck every time you walk alone. His obsession has matured to the point of becoming dangerous: it is no longer enough for him to look, now he wants to possess. He has decided that the time of shadows is over and that, whether you like it or not, you have always been his.
