The series follows Koyuki Hikawa, a reserved high school student who struggles to get close to others, and Minato Amemiya, who continues to approach her. Their story unfolds alongside those of Miki, a popular girl, and Yōta, a laid-back boy.
Agasawa serialized the manga on the LINE Manga app from January 2020 to April 2022. Shueisha published the 14th and final collected volume in February 2025.
