YOU SAID:
Get out fast, before they realize you’re gone
INTO JAPANESE
彼らがあなたがいなくなったことに気付く前に、早く出て行け
BACK INTO ENGLISH
Get out early before they realize you're gone
INTO JAPANESE
彼らがあなたがいなくなったことに気付く前に早く出てください
BACK INTO ENGLISH
Get out early before they realize you're gone
That didn't even make that much sense in English.
