Synopsis
Welcome back, my husband. This is the world's first maid cafe "Todoroki" operated by Maid Robo. This so-called "Hana" or "Hana No. 1" is good at peeping, sexual harassment, underwear mud, etc. Please be careful of new maids and female masters. In addition, we have a variety of items such as the manager with cool glasses, Toki, a new maid with a temperament, and Io, an active high school student with superhuman strength. At the end of the book is their secret. This can only be enjoyed by the owner who requested it. Although the store is often broken, we always welcome your husband from the bottom of our hearts. Thank you for your cooperation.
