Itsuki Hashima is a popular, young novelist. However, he is obsessed with little sisters and his works seem to always include little sisters, so there’s some difficulty coming up with a new series. One day, his younger step-brother Chihiro and his colleagues, Hayato Fuwa, Nayuta Kani, and fellow college student, Miyako Shirakawa show up at his apartment. They enjoy dinner, drinks, and a game. That night, Nayuta makes advances towards Itsuki, but...
That's when the novelist who had come to

Cuando llegó el escritor,
se dio cuenta de que pasaba algo
C’est alors qu’un écrivain arrive

Foi aí que o novelista, que tinha acabado de
 chegar, percebeu que havia algo de errado,
А когда в издательство пришёл писатель,
он сразу заметил неладное.
