Inspector Rinna is a hardworking, serious policewoman who has earned the respect of everyone around her. Lately, though, she is having trouble with her work because she keeps losing focus, and the lapses happen only when Meishi, a detective she works with, is nearby. So she makes a choice. Rinna, who does not know what love is, tries dating as one half of a pseudo-couple. The setup mixes romance, comedy, ecchi, mystery and action.
