Reception
Cho jung bin, writing for the youth magazine Cultura in the year 2023, thought the film did not age well because of how the film deals with the matter of consent, and discusses how the film tells only the men's side of the story, when it clearly depicts sexual harassment and rape by the male protagonist yet minimizes its impact.
