Araiya-san!: Ore to Aitsu ga Onnayu de!?

Souta begins working at his family's public bath, washing customers' backs as part of the job, when his classmate Aoi visits while trying to hide her identity. She does not initially realize that Souta is the person attending to her, and he never expected to meet the girl he knows from school in such an awkward setting. Once the misunderstanding is exposed, their familiar bickering takes on a new closeness, and Souta begins to realize that Aoi's sharp attitude may have been hiding feelings she never knew how to express.
