歌曲歌词
Falling into the sunset
随光走远
所谓时间也无法让回忆妥协
I search for truth My friend
Among reason and emotion
孤单的人 慢慢数时针
被谎言邀请几番
没有答案
曾经的羁绊 也被光阴打散
It's time to move my friend
It's time to face the world again
释怀的夜晚 谁的悲欢
Feel like my life will never be the same
Feel like the pain will sudden be the light
Some people lose their faith but some dreams come true
People come and go I see the rainbow
被谎言邀请几番
没有答案
曾经的羁绊 也被光阴打散
It's time to move my friend
It's time to face the world again
释怀的夜晚 谁的悲欢
Feel like my life will never be the same
Feel like the pain will sudden be the light
Some people lose their faith but some dreams come true
People come and go I see the rainbow
Feel like my life will never be the same
Feel like the pain will sudden be the light
Some people lose their faith but some dreams come true
People come and go I see the rainbow
