YOU SAID:
today is going to be the day that I'm going to throw it back to you
INTO JAPANESE
今日は私があなたにそれを返すつもりの日になるでしょう
BACK INTO ENGLISH
Today will be the day I will return it to you
INTO JAPANESE
今日は私があなたにそれを返す日になるでしょう
BACK INTO ENGLISH
Today will be the day I will return it to you
That didn't even make that much sense in English.
