She would insist she's not close to Bucky or anyone else, and with the exception of Bucky I'd be inclined to agree with her. There are those she talks to semi-regularly, but typically there aren't many deep heart-to-hearts. I definitely think she'll be able to bond more with others going forward, however - Freya and Morgana are both people she'd easily relate to in the "my powers are dangerous help" sense, Sakura, Yuuki and Yona in the "sweet girlfriends who kinda remind her of Anna" department, Arthur and her could bond over overwhelming royal duties and complicated views on magic, and I think Korra, Kya and Merlin might be people she'll bond more with as she starts to practise her magic more. Just to name a few; I'm sure there are plenty of others she could get along with. Kaname if we ever get one in the game again.
Culture-wise, what's been hardest for Steve to adjust to in the modern era?
