Hello, don't be sorry to ask. Usually we are quite open to derivative work, especially for a story like this who is intented to be cathartic, but we just need more precision about what you want to do exactly ^^ Like you want to use the story but rewrite it your way or make some alternative content with the characters/universe? A translation? Where will it be published? This kind of things. Feel free to answer here, or to join our discord to have a more lively conversation^^
