Well, fanfiction exists because the original is full of regrets, doesn't it? I hope my story makes everyone happy, and that you'll leave a comment. Thank you for your support!
I'm just an ordinary, utterly unremarkable author who likes writing sweet romance, so my stories usually lean toward all pairings!
The biggest difference from the original is that Akutagawa sees protecting his sister as the reason for his existence from the very beginning.
What if Ryunosuke Akutagawa were just an ordinary, utterly unremarkable siscon?
Ryunosuke Akutagawa: "The meaning of my existence is to protect my sister!"
Osamu Dazai: "I thought you said your reason for existing was to be my dog in the future..."
Ryunosuke Akutagawa: "I know about the title of King of the Sheep."
Chuya Nakahara: "The Heartless Hound isn't really heartless, after all."
Gin Akutagawa: "Nii-chan..."
Ryunosuke Akutagawa: "Gin, you don't have to say anything. I understand."
Kajii: "Dear big brother, please let me marry Nadeshiko!"
Ryunosuke Akutagawa: "Rashomon!"
Atsushi Nakajima: "The most important person... who is she...?"
Ryunosuke Akutagawa: "What's it to you?!"
Theme: Ryunosuke Akutagawa is adorable too
