The manga's 12-episode anime adaptation streamed on Netflix in October 2022. VIZ Media, which published the manga in English, describes the series: Anzu must play along in this altered reality before she can return to her normal life, so she begrudgingly makes friends with Tsukasa Kazuki. He unfortunately happens to be one of the hottest and most popular guys at school, and what’s worse, she realizes that he might not even be that bad of a person!
