Makino works as a corporate spy while posing as a part-time employee. He infiltrates Prad., a large U.S.-based company. His mission progresses smoothly until Kamina, the new boss and future CEO, uncovers his true identity. As a result, Makino is required to reside in Kamina's upscale apartment under his supervision. The close quarters may become increasingly difficult to manage.
