I wonder if he knows he's all I think about at night
INTO JAPANESE
私は彼が私が夜について考えるすべてであることを知っているかどうか疑問に思う
BACK INTO ENGLISH
I wonder if he knows that he is all I think about the night
INTO JAPANESE
私は彼が私が夜について考えるすべてであることを知っているかどうか疑問に思う
BACK INTO ENGLISH
I wonder if he knows that he is all I think about the night
