Lyrics
今も黃昏の街に
きらめいてる思い出
そうよ あれからあなたに
似ている人に会うたびにときめく
何度 恋に落ちても
いつもうまく行かなくて...
あなたのせいじゃないの ごめんね
降り始めた雨のせいよ
星の数ほど 恋もあるけど
まだあなたを愛してる
少し無邪気な眼差し
小麦色の微笑み
きっと 優しいあなたの
代わりになれる人なんていないの
空の果てを彷徨う
雲のように切なくて・・・
あなたのせいじゃないの ごめんね
時が経てば忘れるから
だけどお願い 夢の中では
ずっとそばに いさせてね
降り始めた雨のせいよ
星の数ほど 恋もあるけど
まだあなたを愛してる
Ima mo tasogare no machi ni
Kirameiteru omoide
Sou yo arekara anata ni
Niteiru hito ni au tabi ni tokimeku
Nando koi ni ochitemo
Itsumo umaku ikanakute...
Anata no sei janai no gomenne
Furihajimeta ame no sei yo
Hoshi no kazuhodo koi mo aru kedo
Mada anata wo aishiteru
Sukoshi mujaki na manazashi
Komugiiro no hohoemi
Kitto yasashii anata no
Kawari ni nareru hito nante inai no
Sora no hate wo samayou
Kumo no you ni setsunakute...
Anata no sei janai no gomenne
Toki ga tateba wasureru kara
Dakedo onegai yume no naka de wa
Zutto soba ni isasete ne
Furihajimeta ame no sei yo
Hoshi no kazuhodo koi mo aru kedo
Mada anata wo aishiteru
My memories still glitter
In the twilight streets
Yes, your memory flickers alive
Every time I meet someone
who resembles you
However many times I think I'm in love
It never works out...
I'm sorry, it's not your fault
It's the rain's fault
There are as many to love as stars
in the sky
But I still love you
Your slightly mischievous gaze
Your soft smile
I know nobody can replace
Gentle you
It's painful like the clouds
Wandering lonely distant skies
I'm sorry, it's not your fault
In time I'll forget
But please stay by my side
