Narcissus (Double Mustard)

Are you my other half? Yes. I am a being born from your will, existing for you alone. We will be halves who depend on each other for life and death, so please take good care of me, Ry... Ryunosuke.

Hmm? Ryunosuke, what's wrong?

Don't worry. I'll always be here.

I'm sorry. My mental state like this is going to ruin your world, isn't it...?

But you are my entire world.

Warnings: This is a Narcissus-style fic about the two Akutagawas from Bungo and Alchemist, with a lot of content based on the experiences of the Three Yuan Akutagawa in The Life of a Certain Fool. I wrote it out of frustration after watching the first season of Bungo and Alchemist. It contains personal interpretations, and I won't change them to match any later plot developments. Akutagawa-sensei is extremely out of character, so read at your own risk. There will be many cameos from characters in Bungo Stray Dogs. The author is a notorious procrastinator, so sometimes you'll have to remind me to update.

Intended theme: Bungo and Alchemist Akutagawa x Corrosion Akutagawa
