YOU SAID:
I love dancing in the back of an ally
INTO JAPANESE
私は同盟者の後ろで踊るのが大好き
BACK INTO ENGLISH
I love to dance behind allies
INTO JAPANESE
私は同盟者の背後にある
BACK INTO ENGLISH
I am behind the allies
INTO JAPANESE
私は同盟者の背後にいる
BACK INTO ENGLISH
I am behind the allies
That didn't even make that much sense in English.
