A prostitute from Hananoya, O-Taki, has been killed. When Takuboku says, "I saw Kyousuke in O-Taki's room," Kyousuke becomes a prime suspect. Meanwhile, based on the fact that Takuboku's romaji diary was left in O-Taki's room, Kyousuke begins to suspect that Takuboku might have done it. Where does the truth really lie?
And that's how... you made 
your crime seem to be mine.
وهكذا... جعلتَ جريمتك تبدو كجريمتي
Und so hast du dein Verbrechen  …
E intentaste que yo pareciera culpable.
E intentaste que yo pareciera culpable.
Et de cette façon,
E così tu
E, assim, você fez o seu
crime parecer meu.
И так своё преступление
ты сделал моим.
