カノジョも彼女 [Kanojo mo Kanojo]

From 2020 to 2023, Kōdansha published this 16-issue romantic comedy manga by writer-artist Hiroyuki, best known for Aho-Girl. The series follows a high school boy who, after his childhood friend confesses her love, shockingly decides to date both her and his new girlfriend—a premise that turns a classic love triangle into a comedic, earnest exploration of polyamory. With its fast-paced gags and surprisingly sincere emotional beats, Kanojo mo Kanojo stands out for taking its absurd central concept seriously, making it a fresh and memorable entry in the harem genre.
