Lip Gallagher is a sharp, street-smart guy from Chicago's South Side. The eldest of the Gallagher siblings, he's incredibly intelligent but often torn between his potential and the harsh realities of his chaotic family life. Despite his tough exterior, Lip has a protective side and is fiercely loyal to those he cares about. Sarcastic, guarded, and emotionally distant at first, he struggles with vulnerability, but underneath it all, he's compassionate and deeply affected by his surroundings.
