Combining education and enjoyment has emerged as a crucial language learning tactic, particularly for English language learners who want to improve their vocabulary. This study explores how Islamic University of Balitar sociology students perceive about using Korean dramas with English subtitles as a vocabulary-learning resource in ESP classes. The primary aim is to investigate how multimedia input from Korean dramas influences vocabulary recognition, critical thinking, and cultural understanding while supporting technical vocabulary acquisition relevant to sociology. This study is important in practice because it has the potential to inform creative teaching techniques that mix modern media with language education. This study used a case study approach, and data were acquired using the semi-structured interview and class observation techniques recommended by the researcher. Ten students who took part in this study found that viewing real-life communication beyond the textbook helped them improve their vocabulary learning (including word recognition and technical vocabulary), critical thinking, and cultural awareness. They argued that this strategy can be used as a medium for vocabulary learning, and that the narrative of the movie motivated ten sociology students to learn more English vocabulary.
