Her boss Nakata is ordered to investigate and visits the place half convinced it cannot be true, only to find Mahiro herself waiting for him. Her bold, seductive persona is nothing like the reserved woman at the office, and he is immediately captivated. Although she worries after unexpectedly getting involved with a coworker, Mahiro becomes intrigued by Nakata’s surprisingly submissive side and begins secretly teasing and servicing him at the office too.
