Akinai Ningyo to Soku no Hatsukoi

Sara is a mermaid navigating the complexities of the modern world, making her living as a merchant who brokers deals between humans and yokai. To her, people are nothing more than clients to be managed, and she has long since decided that trusting anyone with her heart is simply out of the question. Her carefully guarded existence shifts when a mysterious young man named Sora unexpectedly wanders into her secluded miniature garden. Though he shows no signs of hostility, there is something undeniably unusual about him that sets him apart from her ordinary customers. Seeing an opportunity, Sara proposes a transaction, expecting another routine exchange. However, the situation takes a startling turn when Sora reveals what he truly desires: not goods or favors, but Sara herself. Caught off guard by this unexpected demand, she finds herself drawn into a complicated new dynamic. What begins as a simple business arrangement quickly evolves into an intimate cohabitation romance, weaving together hidden secrets and blossoming affection—all sparked by a single, unforeseen deal.
