Liar·space (Dual Protagonists of Opposite Genders GL+BL+GB+BG)

If everyone in this world is a liar... What? Are there no innocent people? Innocent people can only be cannon fodder. One female liar + one male liar, but please believe that this is not BG, nor GB, nor BL, nor GL. This is just a game, and we are all in the game - that's all. A bloody showdown between crooks, but pay attention, mortals, this is not a liar's space, but a liar's space. Or maybe, no CP? Young man, this is really hard to say! Please believe it, this is a game... That's it... That's all.
