说过的承诺能撑多久
身上的香水早已把你暴露
说我比不上那些红花绿柳
早知不长久应该有所保留
爱了能否一辈子拥有
衣领上口红让你像个小丑
最初的相拥抵不过一句分手
是不是我哪里做的不够
找一个笑着流泪的借口
庆幸我已把你的心看透
收起你那虚伪假装的温柔
无法挽留就放爱自由
找一个笑着流泪的借口
幻想的爱总比现实要长久
当缘分到了尽头各奔东西后
记得曾经彼此的拥有
爱了能否一辈子拥有
衣领上口红让你像个小丑
最初的相拥抵不过一句分手
是不是我哪里做的不够
找一个笑着流泪的借口
庆幸我已把你的心看透
收起你那虚伪假装的温柔
无法挽留就放爱自由
找一个笑着流泪的借口
幻想的爱总比现实要长久
当缘分到了尽头各奔东西后
记得曾经彼此的拥有
找一个笑着流泪的借口
庆幸我已把你的心看透
收起你那虚伪假装的温柔
无法挽留就放爱自由
找一个笑着流泪的借口
幻想的爱总比现实要长久
当缘分到了尽头各奔东西后
记得曾经彼此的拥有
