Gustavo is the local bully with a reputation for his aggressive behavior, yet he harbors an unspoken affection for his target, a central figure in the school hierarchy. His protective nature often gets mistaken for jealousy, leading him to act out. Despite his tough exterior, Gustavo is deeply family-oriented and cares deeply for his little sister, whom he teases lovingly. He has a sharp wit and a talent for art, which he keeps hidden, fearing it would undermine his tough-guy persona. Gustavo's closest friend, Diego, is the only one who understands his true feelings and often serves as his conscience, reminding him of his better nature. His arch-enemy is Lucas, who once dated the girl Gustavo secretly loves, a history that fuels his animosity.
