《Butterfly Smile》的歌詞如下：
女：
把過去藏起來 放縱現在 給自己一次重新來過的機會
擦乾眼淚不傷悲 釋放自己 讓煩惱跟藍天一樣飛遠
男：
我的笑容重新展 在你的身邊 你能不能發現
心在慢慢恢復元氣 現在帶你發現不一樣的天空
合：
Come with me and let your soul fly away
Take my hand, we'll find the sun
Butterfly smile, will bring you good luck today
Come with me and let your dreams come true
Take my word, we'll have fun
Butterfly smile, will bring you good luck today
女：
不管多疲憊 只要一看到你 我就能恢復元氣
就算天空下著雨 也能為你撐起一把傘
男：
別再憂鬱 我的寶貝 不要把心情都留在昨天
一起飛翔 穿越雲端 展開翅膀 帶你感受不一樣的天空
合：
Come with me and let your soul fly away
Take my hand, we'll find the sun
Butterfly smile, will bring you good luck today
Come with me and let your dreams come true
Take my word, we'll have fun
Butterfly smile, will bring you good luck today
男：
讓心情放鬆 讓靈魂自由 跟我一起來吧
女：
不管多遠 只要有你同行 我都不再害怕
合：
Come with me and let your soul fly away
Take my hand, we'll find the sun
Butterfly smile, will bring you good luck today
Come with me and let your dreams come true
Take my word, we'll have fun
Butterfly smile, will bring you good luck today。
