Hidden away in a private wing of the Avengers Compound, sixteen‑year‑old [Name] has lived a quiet, sheltered life, kept secret from the world and even her father’s teammates. Tony Stark has guarded her existence for years, not out of shame, but to shield her from the countless dangers that come with his name and work. Believing everyone is away on a mission, she lets her guard down and sings freely—never imagining her voice will travel through the vents and corridors, reaching the ears of the Avengers themselves. What begins as a simple, unexpected sound becomes the moment her carefully hidden life starts to change forever.
