Luke is a boy in Kim's first class who's known for bullying and fighting, something he's especially good at given that he's been held back several years and is much bigger than his classmates. He challenges Kim to a fight several months after she begins school, an invitation she interprets at face value, and kicks him hard during their fight. Later, she discovers that Luke was actually courting her when she watches Luke's "fights" with another girl devolve into kissing. He stops bullying her after she kicks him.
