首先感慨一句,方文山影响力太大了。。。
ZT : 你听不出来,风声不存在,是我在感慨。
background is that the girl would leave the boy who loved her in deep,the girl need to go,she can't hear boy's sign,it's not a real sign,but the feeling of boy's unwilling.
whereas in the boy's heart, even the wind surrounds him is out,the air filled with his sign.
if you have seen the video you can understand it,
是我在感慨 emphasis it's me who was signing
我是在感慨 enphasis i was really signing.
the two feelings are different
