On a winter day when not only a goldfish kept at a pension in an unpopular ski resort jumped out of its tank and died, but a female college student also died.

I attempted to write a work for the Naro Radio Grand Prize, but it became too long, so I decided to go all out and incorporate many keywords. There are depictions of sexual crimes. Since it involves men, I've added a Boys Love tag. I'm dealing with the delicate subject matter of gender identity and gender dysphoria. A fourth-year female university student died at a pension at an unpopular ski resort. Was it murder or accidental death? If it was murder, how was it carried out? That said, I'm not confident whether something like this would actually be possible. It seems difficult to determine a lethal dose. However, since it's clear that camphor is toxic, please never eat it or feed it to anyone. The scientific name of camphor tree is Cinnamomum camphora, and cassia is Cinnamomum sieboldii Meisn. Cinnamon is Cinnamomum verum. In English, they are all in the genus Cinnamomum, and in Japanese, the genus Nikkei.
