We open the film with the male lead realizing that his movie showing on love and loneliness is putting people to sleep. No one seems interested in what he has to say. Yumi, a ticket seller at the venue, mentions that it might be because there's no people - and she volunteers to act in his next film. What happens next makes reality and film bleed together in a rather beautiful manner that kept me watching. Is the new film reflecting reality? Is reality mirroring the new film? Are the two indeed different but conflated to us real-life viewers? I can't say. But it resulted in a pretty, calm, and mellow short film which I did quite enjoy. But it was definitely a more atmospheric/vibe sort of watch, rather than a story-centric sort of watch.
"Why do you shoot a movie?" "Because it's pretty." "Then you only film things that are pretty, do you?" "If you care about something, then it becomes pretty." And that does seem to be the general idea behind the film.
