It’s been 18 years since you were born
The way you look when you run
I still don’t know
The fun starts now

It’s been
18 years since you were born
How you look in pajamas on a trip
I still don’t know
You’re an adult with much more
To look forward to

The youth you hoped for was abducted by aliens
Only eyes appear in photos of old times

It’s all a mess, but it makes me
Want to get to know you

It’s been 18 years since you were born
Yukata sleeves waving on summer nights
I still don’t know
The fun starts now

It’s been
18 years since you were born
Your voice that sings the school song
I still don’t know
You’re an adult with much more
To look forward to

Discoveries are hidden in this distance
Like the contents of your lunchbox

Those days that were slow and steady
To look back on them now I feel
That we were growing up, just a little

We’ve grown to the heights we used to tiptoe to be
Have you finally reached your goals?
It’s fine if it took until now
Though something we couldn’t see toyed with us
We’re experiencing the beginning

You were born
Memories are like bubbles
As they float to the surface
Full of things still unfulfilled

It’s been 18 years since you were born
How you freak out when the school bell rings
I still don’t know
The fun starts now

It’s been
18 years since you were born
Laughter that rings out after school
I still don’t know
You’re an adult with much more
To look forward to

生まれ落ちて18年か
あの子の走る時の姿も
I still don’t know
楽しみはここから

かれこれ
生まれ落ちて18年か
旅先でのあの子のパジャマも
I still don’t know
ときめきを残した
大人じゃん

期待してた青春は宇宙人に連れ去られ
思い出の写真には目元以外映んなくて

散々だけどその分貴方を
知りたくなるしな

生まれ落ちて18年か
夏夜に揺れる浴衣の袖も
I still don’t know
楽しみはここから

かれこれ
生まれ落ちて18年か
校歌を歌うあの子の声も
I still don’t know
ときめきを残した
大人じゃん

意外性がこの距離の中に隠されてる
例えば昼に食べる弁当の中身とか

地続きで緩やかな日々を
振り返れば僕らは前よりか
ちょっとだけ大人になれているような気がして

背伸びをしてた背丈が等身大になった
憧れてた営みに辿り着けたか
それは今となれば構わない
見えないものに　弄ばれながら
初めてを噛み締めてる

生まれ落ちて
思い出が泡のように
浮かび上がって
まだ足りないことだらけ

生まれ落ちて18年か
チャイムの音ではしゃぐ姿も
I still don’t know
楽しみはここから

かれこれ
生まれ落ちて18年か
放課後に響く笑い声も
I still don’t know
ときめきを残した
大人じゃん
