Seven Seas Entertainment licensed the manga in English in September 2021 and published the tenth volume on March 24. The 11th volume is set to be released on November 17.

Koisuru (Otome) no Tsukurikata was nominated for the Tsugi ni Kuru Manga Awards in the Web Manga division in 2020, 2021, and 2022. The manga also placed in the Should be Anime category in MyAnimeList's 2024 and 2025 editions of You Should Read This Manga.

Synopsis
Kenshirou Midou is a popular student who harbors a secret: despite being a boy, he has always loved the art of cosmetics. Because of his efforts to keep this low profile, only his sisters and Hiura Mihate, a childhood friend, know his hidden obsession. Apart from his siblings, Hiura is Kenshirou's only hope at realizing his potential.

Kenshirou begs Hiura to let him practice applying makeup on him, and when Hiura finally succumbs to his request, the drastic transformation shocks Kenshirou. From the appearance of a dull, slender boy to a charming petite girl, Hiura's new look evokes something in Kenshirou.

On the other hand, Hiura has had feelings for Kenshirou long before his dramatic change. Often watching from the sidelines, Hiura thinks that a romantic relationship with him is beyond his reach. But with the revelation of Kenshirou's unusual hobby, Hiura remains optimistic and decides to devote himself to his friend's passion. As their affection for one another intensifies, the pair slowly develops an unbreakable bond. [Written by MAL Rewrite]
