The 21st issue also published the final chapter of the manga. The manga's 14th and final compiled book volume will ship on November 25.
Yen Press publishes the series in English and describes the story:
“I want a boyfriend too!” When Mai, who has no experience talking to boys and even less with love, meets Kei Kurose when she starts high school, the wrong sort of sparks fly. Kei might be super good-looking—but he treats girls like trash. Mai has no patience for his rude attitude, but when she coincidentally discovers his secret part-time job, she might just have to learn to keep his trust?!
Satonaka launched the series in Margaret in 2021. Yen Press released the third volume on May 27, and will ship the fourth volume on October 28.
