Handlung

High school girl Maika Sakuranomiya has trouble finding a part-time job because of how scary she looks when smiling. However, she is scouted one day by an Italian man who is also the manager of a cafe called Stile.

Maika is given a sadistic trait because of her looks and has to adopt a dominant and cruel persona when servicing customers, particularly masochistic ones. This conflicts with her goal of always putting a smile on her customers faces, and hijinks ensue as she attempts to balance her character with her personality. Mafuyu and Kaho play the "little sister" role and the "Tsundere" role respectively. Both have been working at cafe stile longer than Maika, although Mafuyu is the veteran.
