Sumu Kamiyama originally planned to create a one-shot manga featuring a senior and an underclassman. In the original draft, Kurose was the upperclassman while Haimiya was a junior, and Haimiya was intended to be male. However, being unsatisfied with the draft, Kamiyama swapped their roles, with Haimiya now being female and the senior, and Kurose being the underclassman. Kamiyama gave Haimiya a Kansai dialect because they saw Kansai women as tough, but also because the Kansai dialect had a reputation for being intimidating. They also wanted Haimiya to have the contrast between being intimidating and cute, with the dialect itself adding to that feeling. ==Publication==

Kamiyama originally began posting the series as a webcomic on their Twitter and Pixiv accounts on May 14, 2025. After going viral on social media, it was picked up for serialization by Square Enix, which began serializing it on their Manga Up! web service on November 6, 2025. The first tankōbon volume was published on February 6, 2026; A promotional video featuring Yūko Natsuyoshi as Haimiya was posted on YouTube to coincide with the volume's release. ==References==
