YOU SAID:
this man has stolen the heart I own
INTO JAPANESE
この男は私が持っている心を盗んだ
BACK INTO ENGLISH
this man stole the heart i have
INTO JAPANESE
この男は私の心を盗んだ
BACK INTO ENGLISH
this man stole my heart
INTO JAPANESE
この男は私の心を盗んだ
BACK INTO ENGLISH
this man stole my heart
That didn't even make that much sense in English.
