The film was born out of the idea of actor Kato Masaya in a radio program. He collected short love stories and comics with the theme of unrequited love in the program, selected 8 stories from them to be included in the film, and compiled the selected stories into a book and published as an e-novel. In addition to "Unrequited Love for All", a collection of 8 love stories and 14 popular actors, this project also filmed four other single-house series films. Many fresh combinations were born in the film. Saito Takumi and Hirose Alice performed "Something Blue", Ito Sari and Nakagawa Daishi's "My Nickname is Piggy" is very eye-catching. In the unit "Unrequited Love Spiral" starring Zhiying, she boldly challenged the men's clothing style and attracted attention; Shinkawa Yua and Shison Jun's "Lying Love" is full of pure love atmosphere.
