The Door That Led To You - B.B

When Bucky Barnes stumbles into y/n's apartment unannounced, bleeding and desperate, she doesn't ask questions-she grabs thread, disinfectant, and steady hands she didn't know she had. He's a ghost of a man, hunted and haunted, and she's just someone who knows how to stop the bleeding.

What begins as a single act of mercy becomes a fragile routine: late-night knockless visits, quiet conversations between stitches, and a growing sense of trust neither of them expected. Y/n isn't an Avenger, a spy, or a soldier-but there's something about her calm under pressure, her moral compass, and her refusal to see Bucky as a weapon that changes everything.

When the Avengers meet y/n, she's one hell of a surprise, she isn't a liability. She's an asset. One with instincts that rival Natasha's, resilience that earns Steve's respect, and an emotional intelligence that helps Bucky reclaim pieces of himself he thought were gone forever.

As danger closes in and loyalties are tested, y/n is forced to decide whether she's willing to step into a world of gods and monsters-and whether loving Bucky Barnes is worth the risk that comes with him.

Because some wounds need more than stitches to heal.

And some one-time meetings are the start of everything.
