What if you could tell if someone was lying? After an accident, Izaya gains the ability to see lies, which a certain monster happens to be impervious to. Bored with his humans, he decides to toy with the unpredictable man, unaware that Shizuo has secrets of his own. Shizaya

"The human heart is such a fragile thing...isn't it, Izaya?" There's a new mastermind in Ikebukuro, and the information broker has found his match. Shizuo is missing, Shinichi is amused, and Izaya's heart is breaking. Shizaya. 'May the best man win, Orihara.'

An annoyed Izaya deals with a happy, drunk Shizuo. Shizaya crack. Plot later on. Complete with timeline included.

In which Shizuo knows Descartes, Izaya knows he's in a fanfic, and the fourth wall is shattered beyond reparation. Shizaya crack. It is just a game after all.

He knows the fragility of the human heart, and he knows for the one which belongs to that man, he has to break it before he can win. Because Izaya is human, and his heart can be broken. And so he will shatter it, so that he can pick up the pieces and put them back together to form a heart which will belong to only him.

Before he gained his monstrous strength, he knew a girl who was kind to the unsociable him. Before he started loving humans, he knew a boy who accepted the lonely him. But leaving without a goodbye brings pain to both hearts. There's no way the flea can be his Iza-chan, and it's impossible for that monster to be his Shizu-chan. Slight AU Shizaya
