In the series 'Boruto: Naruto Next Generations', it's not revealed who Boruto marries or ends up with. Boruto's romantic relationships, much like his father Naruto's at his age, are currently minimal and undeveloped. One thing is certain though, the series has done a good job of exploring and enhancing the characters and their bonds, and I'm excited to see what happens in the future.
Personally, I have a soft spot for Boruto and Sarada's friendship, as their dynamics remind me of the playful and argumentative relationship between Naruto and Sasuke.
