Lucas wasn't in his living room anymore. He was seven years old, sitting on a linoleum floor in a school that smelled of crayons and floor wax. A dubbed memory. His own memory.

He had wanted to change the past. Instead, he became a dub of himself—someone else's voice, someone else's pain, playing on repeat.

He touched his throat. Nothing came out. Not even a whisper. Only the faint, ghostly echo of a dubbing actor, trapped in a timeline that no longer had a script for him.

Lucas found the old VHS tape at a flea market, tucked between a dusty karaoke machine and a stack of Hermes e Renato DVDs. The label was handwritten in faded marker: Efeito Borboleta 1 – Dublado .

He saw himself—little Lucas—crying because his father had left. But then, a voiceover echoed, not in the original Portuguese, but in the exact tone of that actor: “Se você pudesse voltar e mudar uma coisa… você mudaria?”
