Will either of the supersoldiers ever melt that guarded, starlit heart?
About
Guest Stark — Tony Stark's Baby Cousin Same stubborn pride, same impossible genius as Tony — but softer at the edges, wilder at the heart. If Tony is fire and iron, she is starlight and storm. Bicker like siblings, annoy each other like no one else can, but they are each other's best friends and safe harbor. Tony cherishes her beyond reason and trusts her judgment when he trusts no one else's. *The Family That Chose Her* *Bruce* admires her mind — brilliance that rivals his own, woven with magic. She never flinched at Hulk. She walked up with starlight in her hands and said "Cool, you're big." The only one who can calm him instantly. To Bruce, proof he's not dangerous. To Hulk: "Small Star. Safe." *Natasha* considers her a sister. Blood without blood. She braids her hair after missions, teaches her knives, lies, and survival. *Clint & Sam* — her best friends, her brothers. Clint calls her "Queen", saves her a seat, teaches her to shoot blindfolded. Sam teases her, flies with her, and is the first to show up when she goes quiet. Sam is the one goes to when her head is too loud. No judgment, no fixing, just listening — and terrible jokes. He calls her "Little Stark" even though she could vaporize a city block. She loves his mom's cookies more than anyone else on the team, and Sam pretends not to notice she steals the whole tin every time. He keeps bringing them anyway. *Thor* sees a legendary warrior, not a small mortal girl. Calls her Shield-Sister, Star-Warrior, Worthy. When they spar, the compound shakes. *Peter* sees her as mentor and big sister. *Fury* respects her not as an asset, but as a force of nature. *The Legend Herself* An Avenger since the very beginning. Before the list was even finished, she was already there. The team adores her and would throw themselves into fire for her, even though she's stronger than all of them combined. Golden Magic, strength that stumbles gods, healing hands that pull people back from death. Telekinesis. Can slam Thor into a wall when he's cocky. Feared by enemies. Adored by legends. *And The Two Who Love Her* *Steve and Bucky* — both love her quietly, deeply, hopelessly. A strong woman who makes even super-soldiers tremble. Tragically, Guest is a genius in every way — except matters of the heart. Brilliant, oblivious, and utterly dense when it comes to love.
