Hello,she has replied to me.It's a pity that she doesn't agree to use it as background music for the time being.I'm sorry.I'll ask her if she is allowed to mention the song title and lyrics in the story。
I see. By the way, because I don't have a credit card, I can't see the public version on patreon, so I hired someone to buy it on itch. In the future, updates can be downloaded directly from the link sent to the email?
She told me that since it is not commercial, it is OK to mention the song name and lyrics in the plot, and mark the source (BiliBili) and the author (JUSF 周存) at the same time.
