After Natsu breaks up with Lucy, she wants to make him jealous, so she flirts with Gray. It works...too well! Natsu slowly grows insane as he sees Lucy and Gray happy together. Will he snap? Will Gray free Lucy's heart from its desire for revenge? Or will they all fall victim to this "super psycho love"? Based on the GrayLu/NaLu AMV. Spicy, but very dark.
