YOU SAID:
I hate everything but you
INTO JAPANESE
私はあなた以外のすべてが嫌いです
BACK INTO ENGLISH
I hate everything except you
INTO JAPANESE
君以外は何もかも嫌いだ
BACK INTO ENGLISH
I don't like everything except you.
INTO JAPANESE
私はあなた以外のすべてが好きではない。
BACK INTO ENGLISH
I don't like everything except you.
That didn't even make that much sense in English.
