Although Kaoru Mitazoma (voiced by Masahiro Matsuoka) is a strong man, he is engaged in the housekeeping industry, which is mostly female employees. Kaoru Mitazoma is agile and neat, and is proficient in various cleaning techniques. What's more unusual is that he seems to be better at finding the dark side and weaknesses of his employer's family and repairing their scarred hearts. Yoichiro Ozu Same (played by Itao Soro), who appears arrogant and arrogant on the surface but is empty and precarious on the inside, Mai Kiyama, a female anchor who has a very high popularity in front of the screen but has a very chaotic private life, Fukuko Kasugai, a nanny who is conscientious and has extremely high requirements for her work, and Mitsuko, a newlywed woman who seems happy but is actually full of loopholes, Kaoru Mitazoma uses clever means and superb detective skills to tear off their disguises step by step, exposing the truest human nature.
