The proprietress of the public bathhouse likes it hot.

After losing her father and mother, Maki runs the store with the help of Tatsuhiko, who has been a servant for a long time. She was liked by everyone because of her bright personality, but her customers were all people with quirks and were very busy! One day, she uses her body to encourage Yamada, who is disliked by her colleagues, and another time, she uses her mouth to serve a man who threatens to ask Yamada, and another day, she transforms a boiler worker into a fine man...it's already hard! Please come to the public bath where there is such a naughty and wonderful proprietress!
