The line comes from Ranma ½, the anime adaptation of Rumiko Takahashi’s martial-arts romantic comedy manga. Akane Tendo is one of its central characters and frequently responds to Ranma’s impulsive behavior with suspicion or frustration. The television anime premiered in Japan in 1989 and later reached international audiences through translated releases. Short dialogue excerpts like this one remain useful in anime edits and reaction posts because Akane’s meaning is understandable even without the surrounding episode context.
