First Love and Unrequited Love is a romance anthology that gathers short stories by multiple creators, each exploring the joys and pains of early romantic feelings. The collection centers on two intertwined themes: the sweet, tentative excitement of a first love and the bittersweet ache of an unreciprocated crush. The stories unfold in everyday settings such as school hallways, summer festivals, and quiet neighborhoods, where characters navigate the awkwardness of confession, the thrill of mutual attraction, and the loneliness of loving someone who does not feel the same way.

The anthology features contributions from authors and artists including Rika Enoki, Yōko Nogiri, Truffle, Yukichi Nakamura, and Arika Yaya. Each tale offers a distinct narrative arc: some follow a shy student who finally gathers the courage to speak to the person they admire, while others depict the slow realization that a close friendship may be hiding deeper feelings on one side only. A recurring motif is the contrast between fleeting moments of happiness and the lingering sorrow of what might have been. The characters range from middle schoolers experiencing their first crush to young adults confronting unspoken attachments, giving the collection a broad emotional spectrum.

Notable arcs include a story about a girl who secretly pines for her childhood friend, only to see him fall for someone else, and another where a boy discovers that his seemingly perfect first relationship is built on misunderstanding. The anthology does not follow a single continuous plot but instead weaves together vignettes that highlight the universal vulnerability of romantic longing. Through these varied perspectives, First Love and Unrequited Love captures the delicate balance between hope and heartbreak that defines the experience of loving someone for the first time.
