這世界太過複雜 難分真假
當心聲變得沙啞 只剩牽掛
在這繁華的喧譁 拚命掙扎

等待光芒穿越陰霾
終有一刻 會展翅高飛
別讓眼淚無處可退

其英文歌詞為：
Verse 1:
In this complicated world, it's hard to tell what's true from what's false.
When the voice within fades, it's only loneliness that remains.
In this hustle and bustle, striving for the bright lights,
Not wanting to let my soul become superficial.
Chorus:
Don't let your dreams be buried, keep them hidden inside.
Waiting for the light to break through the haze.
Someday, it will soar like an eagle, don't let your tears fall aimlessly.
Verse 2:
When the sun shines down, brightening every corner,
The rainbow's radiance guides the way, giving courage to the heart.
Let the brave heart not wander aimlessly.
Chorus:
Don't let your dreams be buried, keep them hidden inside.
Waiting for the light to break through the haze.
Someday, it will soar like an eagle, don't let your tears fall aimlessly.
Bridge:
Every smile has the power, every moment is worth cherishing.
Dreams take off, never giving up.
Chorus:
Closing:
This world is no longer complicated because of you by my side.
