It was serialized online between January 2018 and February 2021 on the Japanese novel self-publishing website Shōsetsuka ni Narō.

Rei Ohashi, an ordinary office worker finds herself reincarnated as Rae Taylor, the heroine of her favorite otome game, Revolution.

I'm in Love with the Villainess was originally serialized online from January 14, 2018 to February 21, 2021 on the user-generated novel publishing website Shōsetsuka ni Narō.

[8] On March 19, 2021, Seven Seas issued a statement that they would be releasing a new version of the first volume due to the localization decisions in the original omitting several paragraphs.

[32] A 4-chapter cooking spin-off manga illustrated by tsuke, titled I'm in Love with the Villainess: Maid's Kitchen (私の推しは悪役令嬢。メイドキッチン, Watashi no Oshi wa Akuyaku Reijō Meido Kitchin), was serialized in Comic Yuri Hime from June 16 to September 15, 2023.

It was produced by Platinum Vision and directed by Hideaki Ōba, with scripts written by Ayumu Hisao, character designs handled by Yōko Satō, and music composed by Noriyuki Asakura and Usagi to Uma.

[57] In Anime News Network's Fall 2020 Light Novel Guide the series was generally received positively, though not as strongly as other yuri titles released at the time.

However, it was noted that "if Rae and Claire both start off as almost intensely difficult to like, they do undergo enough of a change by about midway through the novel that makes them much easier to root for.

Kevin Cormack of Anime News Network praised it for reinstating segments, missing from the first English-language print run, which explain Rae's motivations, and said that the narrator, Courtney Shaw, nails down the many-faceted personality of Rae, and the voices of other characters, and hoped for an audio adaptation of volume 2.

[69] However, Andrew Henderson of Anime Feminist, reviewed the first episode, and was critical of the series for putting a "queer spin" on "stale romantic archetypes" and found Rae's actions toward Claire grating, though it was "kinda funny" in small amounts, and hoped that the dynamic between them changed as the series went forward.

[70] A later update on Anime Feminist echoed Henderson's review, saying the series held potential, but was mired in "uncomfortable gags" by Rae toward Claire.
