YOU SAID:
I love myself to the moon and back
INTO JAPANESE
私は月と背中に自分自身を愛する
BACK INTO ENGLISH
I love myself on the moon and back
INTO JAPANESE
私は月と背中で自分を愛する
BACK INTO ENGLISH
I love myself with the moon and back
INTO JAPANESE
私は月と背中で自分を愛する
BACK INTO ENGLISH
I love myself with the moon and back
That didn't even make that much sense in English.
