Happy Bun was developed to meet the emotional needs of relaxation and nostalgia, aiming to reintroduce everyday warmth and human connection into urban life. Centered around street culture, the brand builds social interactions through packaging design and visual storytelling, activating public spaces and community engagement. The project further explored future possibilities for urban street stalls through structural packaging innovation and exhibition design, integrating commercial strategies with cultural insight to propose a sustainable direction for brand communication in urban environments.
