Boku no Gemini  

My Gemini, 僕のジェミニ

John Utterson, with his spectacles and reserved nature, is able to distinguish between the Stevenson twins despite their efforts to deceive each other as Jekyll and Hyde. Despite their contrasting personalities - Jekyll being calm and composed while Hyde is cheerful and expressive - they have been playing this game of pretending for so long that their true selves have become indistinguishable when they are together. However, when one of them tragically passes away, their identities as Jekyll and Hyde are no longer valid, causing even John to question which of his friends has survived.
