Verse 1:
你的泪光 柔弱中带伤
十年前的那场雨 太惊艳
如今天末染霞 我又在这里想你
想到不能再想

Your tearful eyes, gentle yet wounded
That rain from ten years ago, so stunning
Now at sunset hue, I'm here missing you again
Thinking to the point of being unable to think anymore

Chorus:
你演的戏 好像还在昨天
笑着说爱我 到最后
我才发现我只是个配角
在你的世界从未真正存在过

The play you acted in seems like yesterday
Saying you love me while smiling until the end
I only realized afterwards that I was the supporting character
I have never truly existed in your world

Verse 2:
你的脸颊 平静中带伤
十年后的那次相遇 我泪光
如今天末染霞 我地老天荒都爱你
爱到不能再爱

Your cheeks, calm yet wounded
Ten years later, when we met again, my tears flowed
Now at sunset hue, I will love you until the end of time
Loving you to the point of being unable to love anymore

Chorus:
你演的戏 好像还在昨天
笑着说爱我 到最后
我才发现我只是个配角
在你的世界从未真正存在过

The play you acted in seems like yesterday
Saying you love me while smiling until the end
I only realized afterwards that I was the supporting character
I have never truly existed in your world

Bridge:
几次回眸 已不见你
苍白了岁月 我还在原地
如今天末染霞 我又在这里想你
可惜你早已不在我的世界

Glancing back many times, I can no longer see you
The years have passed and I'm still in the same place
Now at sunset hue, I'm here missing you again
Unfortunately, you are no longer in my world

Chorus:
你演的戏 好像还在昨天
笑着说爱我 到最后
我才发现我只是个配角
在你的世界从未真正存在过

The play you acted in seems like yesterday
Saying you love me while smiling until the end
I only realized afterwards that I was the supporting character
I have never truly existed in your world

此歌曲主题是关于爱情中不同角色的存在。歌曲讲述了一个配角在爱情中所经历的心理变化。他曾以为自己与女主角并肩走过完美的爱情之路，但事实上他从一开始就只是女主角的过客。歌曲也强调了时间的流逝和记忆的淡忘。所有的疼痛和回忆只能存在于现实和梦境之中。该歌曲还表达了对梦中情人的思念，和对爱情的失败所带来的痛苦，是一首典型的许嵩风格的情歌。
