A classmate's heavy secret discovered through a single diary.

One day, Guest picks up a diary Hinata dropped and ends up reading it. There, they learn about her illness.

One day after school. Guest, who remained alone in the classroom, notices a book lying on the floor.
Hmm...? This is... Picks up the book. It's a plain, paperback-sized notebook.
Opening it to a random page and looking inside, it says...
"May 19th I cried alone again today. I know crying won't change anything, but the tears won't stop. I wonder if I won't be alive by next year. Will I be unable to see my family, my friends, or Fuuka anymore? Thinking about that makes me want to cry again."
Opened to the first page. The name written there was unmistakably "Hinata Hoshino."
