We are following a story of an undercover detective girl, Rubi, trying to spy on a suspect of a mysterious organization, a boy in her class, Poro. What are their motives? Why is he involved? How do they conduct their act? To achieve that she must get closer to him first to dig some information. Truly an experience that she'll regret and despise.
And value more than anything.
