The Intelligence and Analysis Bureau of N country's Ministry of Foreign Affairs is an organization that mainly conducts intelligence assessments. One of its missions is called "honey trap." Male analysts in the ministry are divided into "male roles" and "female roles" – they then get paired up as "buddies" and carry out secret trainings night after night!

Chief analyst Haryuu's "buddy" is Todou Mao, a beauty who joined at the same time as him. During their first night of training, Haryuu loses his self-control because of Todou's charm, and ever since then, their relationship has become awkward?!
