The study compares themes of love, breakup, identity, fandom engagement, and digital-era distribution; analyzes reception in South Korea, India, and global audiences; and situates both works within broader cultural and industrial contexts (K-pop globalism and modern Hindi cinema). Because the exact texts/titles are ambiguous, the paper uses reasonable assumptions and presents a framework for analysis that can be populated with exact citations when the precise works are identified.
