仕事に追われる日々を送る三十路手前のファミレス社員成田は、 転職の面接結果に落ち込みながら、夕食中に動画サイトでオススメされた動画をぼんやりと眺めていた。そこに映っているのはクールですこし生意気な受け答えをしながらも、圧倒的なセンスと歌唱力を持つアーティスト、夜崎ササ。

その後、洗濯物のトラブルで訪れた古びたコインランドリーで、ふと目にした女性の姿に違和感を覚える。どこかで見たようなその人は、さっきまで動画で見ていたササ本人だった──。 Narita, a family restaurant employee in his late twenties who is always busy with work, is feeling down about the results of his job interview, while he is having dinner, he is absentmindedly watching a video recommended to him on a video site.

The video shows Sasa Yoruzaki, an artist with an overwhelming sense of fashion and singing ability, despite her cool and slightly cheeky responses.

Later, when he goes to an old laundromat to deal with some laundry problems, he suddenly notices a woman and feels something is off about her. The woman seems familiar, but it is Sasa himself, the one he had just seen in the video.
