Details: Lucas fell in love with Peyton the moment he first saw her in the 8th grade. He was very jealous when she began dating his half-brother and rival Nathan Scott during high school. They did not speak to each other until her car broke down in junior year and he towed it back to town. He showed her nothing but kindness and respect and encouraged her dreams. This led her to break off her relationship, realizing she deserved far better. The attraction to each other continued to grow and they shared their first kiss and more but when Lucas made it clear how strongly he felt about her she was uncomfortable and left.
