Who was Huck Finn's girlfriend?

Excuse me, but I'm curious about something regarding the novel "The Adventures of Huckleberry Finn" by Mark Twain. In the story, Huck Finn has many adventures and encounters with various characters, but I was wondering if there was a particular female character portrayed as Huck's girlfriend? If so, who was she, and how did their relationship develop throughout the narrative? Could you please elaborate on this aspect of the story?
