After watching Gintama, I really like Katsura's natural innocence and Gintoki's character. I looked for a lot of fan novels and found that they were all written, directed and acted by myself (forgive me for saying that I am the only one who understands the strange terminology...), So I decided to write this fan story of Gin and Katsura in the same way as the anime is broadcast. That is, the background, characters, and relationships should be as close to the original work as possible, and we strive to let everyone see a fan story that does not violate harmony. That's it!
