A group of artists comes together to create a collection of short manga stories, each centered on the theme of breasts within romantic or comedic relationships between women. These standalone chapters explore a wide range of scenarios, from secret kisses and playful fondling to earnest discussions about the joys and quirks of having a bust. Characters include high school students, adult women, and office workers, all navigating moments of intimacy and humor that revolve around their bodies. The tone is lighthearted and ecchi, mixing affectionate flirting with comedic misunderstandings. The anthology offers a variety of art styles and narrative approaches, with each story presenting its own unique pairing and setting. The first volume was released in October 2020, followed by a second volume in March 2025, featuring a rotating lineup of contributing writers and illustrators. The collection does not follow a single plot or set of characters; instead, it celebrates the diversity of yuri romance through the unifying theme of breasts.
