Spice Visual presents BLUE RIBON label's debut work featuring Koizumi Fuu, a slender, fair-skinned idol with an innocent, studious charm. Standing 148 cm tall, Nana-chan opens up about how she genuinely connected with this role, saying, "There was something about it that mirrored my true self, and I ended up getting serious." The theme of this release is "the secret face shown only to a childhood friend." Though she usually appears quiet and bookish, gentle touches quickly leave her breathless and trembling with subtle tension. Captivated by her vulnerability, she silently runs her tongue over what’s presented before her, locking eyes with quiet intensity. This film captures the pure, irresistible attraction inspired by her true self.
