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?
I went into the room, and less 
than 30 minutes later, I left.
دخلتُ الغرفة ثمّ غادرتُ بعد أقلّ من 30 دقيقة
Ich bin schon nach 30 Minuten wieder
aus dem Zimmer und sofort nach Hause gegangen!
Me fui una media hora
después de entrar.
Me fui una media hora
después de entrar.
Je suis reparti moins d’une demi-heure
après être entré.
Sono entrato in stanza
Eu fui naquele quarto e saí
menos de 30 minutos depois.
Я там и получаса не пробыл.
