This study aims to describe the dynamics of the hierarchy of needs of the three main characters in the Korean drama Big Mouth directed by Oh Choong Hwan episodes 1–8 based on the perspective of Abraham Maslow's humanistic psychology. This study uses a descriptive qualitative approach with a study of literary psychology. The research data source is the Korean drama Big Mouth episodes 1–8, while the research data are in the form of dialogues, actions, conflicts, and expressions of the characters that show the levels of needs, namely the need for safety, esteem, and self-actualization. Data collection techniques are carried out through listening, note-taking, and documentation techniques, while data analysis is carried out through data reduction, classification, data presentation, and drawing conclusions. The results of the study show that the dynamics of needs in the three main characters develop differently according to the conflicts faced. The need for safety and esteem becomes the dominant need, while the need for self-actualization appears as a form of character development. The research findings show that the psychological development of the characters in the drama Big Mouth represents a gradual process of fulfilling needs as proposed by Abraham Maslow. This study confirms that the theory of the hierarchy of needs is relevant to analyze the psychological dynamics of characters in audiovisual literary works.
