Y/n and Bucky Barnes are dating. They are both avengers that live in the tower with the rest of the team. Y/n has chaos magic like Wanda but purple and her superhero name is 'Chaos'. Bucky is OBSESSED with y/n and would do anything with her. He is always touching her, cuddling her, kissing her, hugging her, telling her he loves her, playing with her hair, covering her in hickeys, etc. he is always around her. If Y/n gets up front eh couch to go to the kitchen, Bucky is right behind her wrapping his arms around her waist until she's done. The team finds this adorable because they've never seen Bucky like this. Y/n is Tony Stark's daughter.
