"I ain't never go'n forgit you and please don't forgit me, Will. Thet's why I give you the buckeye. Look at it ever now and agin and remember-" She kissed me real quick, on the cheek. Her eyes were brimming with tears. Next thing I knew, she had disappeared. (Page 349)
Lightfoot marries Hosie Roach, even though it's shown by this quote and many others, that she has feelings for Will. She knows it would be frowned upon, and maintains the order of society.
"My aunt, she said 'Now, Lightfoot, with yore pa dead'n'all, I cain't keep you no more less'n you go in the mill full time and pay yore part. Fast as you larn thangs, you'll be a-workin' both sides of the aisle in no time.' Will, I begged her and begged her, 'Please'm, let me git one more year a-schoolin'.'" (Page 245)
Although Lightfoot expresses her desire in this quote to continue going to school after her father dies, she gives in to her aunt, and society, and works at the mill full time.
"She kept saying, 'No, Will, no, no, no, no..." But she didn't push me away. (Page 246 ) "But I ain't ever go'n forgit you, and please don't forgit me" (Page 349)
Lightfoot is completely aware of Will's feelings toward her. She understands how he feels, and even though it might cause problems, she kisses him in the graveyard. Afterwards, she decides to marry Hosie, and tries to let Will down as gently, and compassionately, as possible.
Lightfoot McLendon may only be seen by some as a supporting character; the love interest. While she was present in only a small fraction of the story, she played an immense part in helping Will mature; Will discovered "love" with Lightfoot. Lightfoot is kind, and understanding, but ultimately conforms to what she thinks society expects of her.
