乘着風 想飛躍彩虹 隨引力墜落
將日常概括 將機會緊握 由我超越我
在雨後的晴空 靜靜地目送
過往的夢 點燃薪火 將我向未來推動
還沒習慣 咖啡的苦 眨眼閉目 嘆氣吐出
嘗試錯誤 開始結束 向着明天 往前一步
trial and error trial and error
good-bye and hello uphill and downhill
trial and error 再往前一步
trial and error
一直都 嚮往着的夢 從久遠閃爍
太陽會日落 喪氣的時刻 它也很難過
仍用力維持着 元氣的笑容
收斂悲傷 藏起失落 全力去傳遞快樂
不甘結束 我的旅途 我已成為 我曾羨慕
一路有夢 從不孤獨 向着明天 往前一步
trial and error trial and error
good-bye and hello uphill and downhill
trial and error 再往前一步
trial and error
就讓我 盡情去試錯 不必想結果
上坡或下坡 都通往日落 還有月等我
如果說一生都 在舞台起舞
還有同伴 就在前路 指引我把光握住
還沒習慣 咖啡的苦 一路有夢 從不孤獨
嘗試錯誤 開始結束 向着明天 往前一步
trial and error trial and error
光 炸開雲火 夢將愛包裹
trial and error 請注視着我
trial and error try continue

I look up, see them in the sky far above the rain
Must be a good life, flying up so high, no chances miss their eyes
But then the clouds open up to the rainbow above
I watch as they all pass me by, so many questions in my mind
When things get tough and the world’s too much
A coffee break with me could be what you need
It’s my time to say 「We’re gonna be okay」
Because with every end another trial begins
Trial and error, trial and error
「Goodbye」 then 「Hello,」 uphill then downhill
Trial and error, one more step forward
Trial and error
I look back, remembering the start before it all went dark
You could be so far and still light up my heart, teenage superstar
But lately I haven’t seen you put that smile on your face
Life can bring you to your knees, so get back up and just believe
When things get tough and the world’s too much
A break with cake and me could be what you need
It’s your time to say 「We’re gonna be okay」
This heartbreak and sorrow might be there tomorrow
Trial and error, trial and error
「Goodbye」 then 「Hello,」 uphill then downhill
Trial and error, one more step forward
Trial and error
In the spotlight, don’t you be surprised if life doesn’t feel bright
Breaking new ground’s the hardest road to take when loneliness awaits
But now I know I’m not alone on this upward slope
One step forward to the sky, this time I’m gonna reach the light
When things get tough and the world’s too much
This next round’s on me 』cause I see what you see
It’s our time to say 「We’re gonna be okay」
Smile 』cause we’re free, tonight we’re gonna dream
Trial and error, trial and error
No need to worry, 』cause we’ve got each other
Trial and error, one more step forward
Trial and error, now press 「continue」
