"Setsuna" did not tell Zhao Youyue that her sickness was beyond cure, but nevertheless, became the best of friends with Zhao Youyue within that short period.
They did not even know the other's real name, but "Setsuna" already felt that she had truly bonded with the girl whose nickname was "Altair."
Unsure if it was an illusion, "Setsuna" felt that Zhao Youyue was her written protagonist in the flesh, as Zhao Youyue was so familiar with her work, as if she had firsthand experience of all the scenes that she had created.
"Setsuna" was both familiar and unfamiliar with her written protagonist, and also with the only fan, who was even her confidant. All their communications had only been on the internet. But whenever she wrote, she always had communications with "Altair" on her soul aspect.
