His Girl (Bucky x y/n)

James Barns was built to survive wars, not to feel. A haunted super-soldier, scarred by violence and memory, lives trapped between what he was made to be and what he's lost. Y/n is the sister of Tony Stark-brilliant, guarded, and tired of living in the shadow of a hero-carrying her own quiet fractures beneath a confident exterior. When fate pulls them together, their connection becomes something neither expected: a fragile refuge in a world that never stops hunting them. As old enemies and painful truths resurface, love becomes both their greatest risk and their only chance at healing.
