Chikage Nakakura launched a manga adaptation on Futabasha's Gaugau Monster website in July 2020. Futabasha published the manga's eighth compiled volume on December 25.
Comico's English website and app Pocket Comics is publishing the manga in a full-color vertical-scrolling version under the title Betrothed to My Sister's Ex, but has not updated the series since November 2023. The black-and-white manga version in Japanese is ongoing.
Tobirano debuted the web novel on the Shōsetsuka ni Narō (Let's Become Novelists) website in October 2019. Futabasha began publishing the light novels with illustrations by Mai Murasaki in April 2020, and it released the eighth volume on January 10.
Seven Seas Entertainment announced in April that it had licensed the light novel series and the manga, and will release them both starting in January 2026. The company describes the story:
Marie has spent her life living under her sister's shadow as the two grew up in an impoverished baron's home. Every nice thing went to Marie's sister, leaving her without even a proper dress! And right when her sister was being married off to a wealthy Earl–tragedy strikes and Marie's sister is killed en route. With the dowry already spent, it's decided that Marie will take her sister's place and become the Earl's betrothed. But, when she gets there, she finds there's been a serious mix-up—the proposal was a total misunderstanding! Can Marie win the heart of the handsome Earl, or is she destined to live a life without a single nice thing?
