Synopsis
Kowloon Walled City, the most densely populated place on Earth, houses over 33,000 residents within a labyrinth of interconnected high-rises spanning just 6.5 acres (2.6 ha). Within this urban enclave lies the Wong Loi Realty Company, where an office romance develops between two coworkers: the easygoing yet brash Hajime Kudou and the reserved Reiko Kujirai, who has been in love with him since first meeting him. Despite their contentious dynamic, the two share a close rapport, frequently having lunch together. Their mutual affection for Kowloon Walled City gradually deepens their bond—yet an underlying peculiarity lingers between them.

A 32-year-old real estate agent residing alone in Kowloon Walled City.
