This project explores the "question mark" as a driving force across different eras. In 'Fairy Tale,' it reveals truths beyond the protagonist's view. In 'History,' doubt acts as an engine for technological and systemic progress. Finally, 'Modern' examines our stagnant, homogenized society, seeking a breakthrough. Expanding from individual shifts to social phenomena, the question mark serves as a tool to unveil the unknown and drive innovation, breaking fixed patterns to keep our world moving forward.
