Having lost his parents in a car crash, Yuuri is left to live in the mansion on his own. One day, a beautiful maid, Lilith, shows up, offering to work for him for free.
I believe it's normal for a maid 
to address her master by name.
.أعتقد أنه من العاديّ أن تنادي خادمة سيّدها باسمه
Es ist doch ganz normal,
dass ein Dienstmädchen
Cela me semble pourtant normal
de s’adresser à son maître de cette façon.
Pensavo che fosse normale per una cameriera
Acredito que seja normal uma criada
se dirigir ao patrão pelo nome.
