I'm a Japanese drama fansubber, and I have absolute confidence in my translation

Hopefully the staff will update the lyrics page without too much editing.
I plan to translate all the Secret albums songs, and any single songs if it isn't already.

Days I spent loving you were my last miracles
The season when anyone and everyone fall in love
Has brought warmth and coldness again this year
Reminiscing days when we didn't know anything because we were immature,
Of days when we laughed as we clung together and walked
How should I explain this surging pain?
All by myself in the snow, even on freezing nights
Loving you is my last courage
Is it too silly just waiting for the time to pass
Believing that I will be forgiven someday?
Embracing the overlowing memories,
While being careful not to spill any
Until the day our hands reach the snow
Loving you is my last courage
Embracing the overlowing memories,
While being careful not to spill any
All by myself in the snow, even on freezing nights
Until the day when our hands reach the snow
Loving you is my last eternity
Having met you is my first miracle
君を愛した日々は 僕の最後の奇跡
kimi wo aishita hibi wa boku no saigo no kiseki
誰もが皆 人恋しくなる季節が
daremo ga mina hito koishikunaru kisetsu ga
今年もまた あたたかさと冷たさを
kotoshi mo mata atatakasa to tsumetasa wo
連れてやって来た
tsurete yattekita
幼すぎた僕らがまだ 何も知らず
osanasugita bokura ga mada nanimo shirazu
笑い合ってしがみついて 歩いていた日を
waraiatte shigamitsuite aruiteita hi wo
思い出す
omoidasu
押し寄せるこんな痛みに
oshiyoseru konna itami ni
どんな言い訳をすればいい
donna iiwake wo sureba ii
白い雪にひとりで 凍えそうな夜でも
shiroi yuki ni hitori de kogoesou na yoru demo
君を愛しているのは 僕の最後の勇気
kimi wo ai shiteiru nowa boku no saigo no yuuki
いつかきっと 許されると信じながら
itsuka kitto yurusareru to shinjinagara
時間がただ 過ぎてくのを 待つのは
jikan ga tada sugiteku nowo matsu nowa
愚かすぎるのかな
oroka sugiru no kana
溢れる想い抱きしめる
afureru omoi dakishimeru
こぼれてしまわないように
koborete shimawanai youni
白い雪にふたりの 手が届くその日まで
shiroi yuki ni futari no te ga todoku sono hi made
君を愛しているのは 僕の最後の勇気
kimi wo aishiteru nowa boku no saigo no yuuki
溢れる想い抱きしめる
afureru omoi dakishimeru
こぼれてしまわないように
koborete shimawanai you ni
白い雪にひとりで 凍えそうな夜でも
shiroi yuki ni hitori de kogoesou na yoru demo
白い雪にふたりの 手が届くその日まで
shiroi yuki ni futari no te ga todoku sono hi made
君を愛しているのは 僕の最後の永遠
kimi wo aishiteru nowa boku no saigo no eien
君に出会えた事は 僕の最初の奇跡
kimi ni deaeta koto wa boku no saisho no kiseki
