Bella Swan and Edward Cullen first meet in the small town of Forks, Washington, where Bella moves to live with her father, Charlie Swan, after her mother remarries. It is the beginning of the school year, and Bella is attending Forks High School.
On her first day at school, Bella is immediately drawn to a mysterious and strikingly beautiful group of students, the Cullens. Edward Cullen is among them, and he stands out to Bella due to his otherworldly looks and the fact that he seems to be the only one who is not immediately friendly towards her.
In their biology class, Bella is seated next to Edward, and their initial interactions are marked by a mix of curiosity and awkwardness. Edward exhibits unusual behavior, appearing repulsed by her presence and abruptly leaving the class on her first day. Over time, however, Bella and Edward find themselves inexplicably drawn to each other, and Edward's true feelings towards her begin to surface.
Throughout the story, it is revealed that Edward's initial reaction to Bella was a result of his struggle to resist the scent of her blood, which is particularly appealing to him due to his vegetarian vampire lifestyle. As they get to know each other, they fall deeply in love, despite the challenges posed by Edward's vampiric nature and the dangers their relationship presents.
Their meeting marks the beginning of their extraordinary and complicated love story, setting the stage for the events that unfold in the rest of the Twilight series.
