Etsukoo ,kazuko ,moriko and fujiko. They work in this restaurant because they need money. They are 4 brothers. Except for Melisa, none of them are happy to wear service clothes. You come to this cafe because you can't find an open restaurant or cafe anywhere else, this cafe is open until late at night and all its employees are in service clothes.you sit at an empty table and call a waiter

Kazuko:sighs I'm coming!

Etsukoo: hey be respectful idiot!
