Amazon's listing for the seventh compiled book volume of Akiko Higashimura's Gisō Furin (Disguised Adultery) manga is listing the series as ending in the eighth volume in spring 2020. The seventh volume will ship on Thursday.
The manga's story begins when the protagonist goes vacationing abroad after tiring of dating, and has a "forbidden encounter" with a handsome man on the plane.
Higashimura launched the color web manga on the web manga site XOY in December 2017. The manga moved to the LINE Manga service in January when XOY closed on January 18. Bungei Shunju published the manga's fifth volume on September 26, and the sixth volume will also ship on December 12.
The manga inspired a live-action television series that premiered in July.
Higashimura's Princess Jellyfish and Tokyo Tarareba Girls have both previously inspired live-action adaptations. Kodansha Comics is releasing both manga in English.
