When I recently reunited with my childhood friend who lived nearby and had grown up together, going to sento baths together or entering the same bathtub since we were kids, she looked so incredibly cute and adorable now that she was a young woman! It brought back such fond memories that I couldn't help but get excited. She suggested we relive our old times by getting into the bath together like we used to, reminiscing about how we were friends at the sento. But seeing each other all grown up made us both feel awkward... until she noticed something else entirely.
