This series is based on the live-action adult video titles, codes PFES-044 and HUNTC-243, from Hunter.

Kazama Hiroshita manages to survive his first week as an employee at a "lingerie research" office, as well as the only guy living at the dorm with his fellow employees. Luck(?) would be on his side as he shares a room with a 1st-person-shooter-playing fujoshi. He would also "enjoy his time" with another fellow employee who's a "shemale."
