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.
If it turns out you're useless, 
I'm throwing you out.
.إن اتّضح أنك دون فائدة فسأقوم بطردك
Wenn sich herausstellt, dass du
nutzlos bist, werfe ich dich raus.
Si eres una inútil, te echaré.
Si eres una inútil, te echaré.
Si tu travailles mal,
j’hésiterai pas à te virer.
Se non sarai all'altezza, non esiterò a cacciarti.
Se eu notar que você não é útil,
vou mandá-la embora logo em seguida.
И если толку от тебя не будет —
мигом за дверь пойдёшь.
