[Verse 1] Today, I'm home alone (今日は家に俺一人) My wife and kids are out somewhere (妻も子供も出掛けてる) I open up my eyes (目を覚まして) And look at the clock (時計を見たら) I'm running a little later than usual (いつもより少し遅かった) I wash my face (顔を洗って) Skip my coffee (コーヒーは諦めて) Throw my clothes on in a hurry (急いで服を着替えて) And walk out the same front door (いつもの玄関を出る) Nothing's different for me (俺だけいつもと変わらない) Or at least, that's how it seemed (はずだったけど) There's only one thing different today (一つだけ違うのは) I'm the one (今日は俺が) Who has to lock the door (鍵を閉める) That's all. (それだけだ。) [Verse 2] Ten minutes down the road (家を出て十分) At the second light, it hits me (二つ目の信号で思い出す) Did I lock the door? (鍵、閉めたっけ) I know I had the key (確かに手には持ってた) I know I closed the door (ドアもちゃんと閉めた) I think I turned the key (鍵を回した気もする) I think I heard it click (音も聞いた気がする) Should I go back? (戻ろうか) No, it's too late (いや、もう遅い) The light turns green and pushes me on (青になった信号に押されて) So I keep driving to work (そのまま仕事へ向かった) [Pre-Chorus] Locked or unlocked (閉めたとか 開けたとか) While I'm thinking about things like that (そんなことを考えてたら) The things I said back then (あの時言ったこと) The things I didn't say (言わなかったこと) The things I saw (見てしまったもの) The things I pretended not to see (見なかったことにしたもの) Even things that don't matter (どうでもいいことまで) Start coming back to me (思い出していた) [Chorus] You can't say you shouldn't have opened it (開けなきゃよかったなんて) Until you've opened it (開けたあとにしか言えない) If I'd never known (知らないままでいたなら) Would I still be in the same place? (今も同じ場所にいたのかな) Things I kept safe by keeping them locked (鍵をかけたまま守れたもの) Things I saw because I opened the door (鍵を開けたから見えたもの) Which one was right? (どっちが正しかったなんて) I don't have to decide yet (まだ決めなくていい) [Verse 3] Things I didn't have to say (言わなくてよかったこと) Answers I wish I hadn't heard (聞かなきゃよかった答え) Sometimes it's true (そんなことも確かにある) You're happier not knowing (知らない方が幸せだった) But even now (それでも) I sometimes think about (今でもたまに考える) What was behind the door (扉の向こうを) I never opened that day (あの日、開けなかった) Maybe wondering about it (それを考えてる方が) Is more trouble anyway (面倒だったりする) [Pre-Chorus 2] I learned I couldn't go back (戻れないことを知ったのは) Not because I moved ahead (進んだからじゃなくて) But because (ただ) I'd already opened the door (一度、開けてしまったから) And still (なのに) I remember what happened that day (あの日のことは覚えてるのに) But I can't remember this morning (今朝のことが思い出せない) [Chorus] You can't say you shouldn't have opened it (開けなきゃよかったなんて) Until you've opened it (開けたあとにしか言えない) Even knowing it might hurt (傷つくことを知ってても) There are days I reach for it again (また手をかける日がある) Things I can protect by keeping them locked (鍵をかけたまま守れるもの) Things I'll never reach unless I open the door (鍵を開けなきゃ届かないもの) Whichever one I choose (どっちを選んだとしても) Something stays on the other side (何かは向こう側に残る) [Bridge] I don't have to open everything (全部開ける必要はない) I don't have to lock everything away (全部閉じる必要もない) Some things don't need to be said (言わなくてもいいこともある) Some things I don't need to know (知らなくてもいいこともある) Still (それでも) If I'm the one who opened the door (自分で開けた扉くらい) I want to see it with my own eyes (自分の目で見てみたい) Thinking about things like that (そんなことを考えながら) Another ordinary day goes by (いつもの日常が過ぎていく) [Final Chorus] Even if I wish I'd never opened it (開けなきゃよかったとしても) I don't have to erase the fact I did (開けたことまで消さなくていい) Even if there's nothing on the other side (向こう側に何もなくても) I can always just turn back (それならそれで戻ればいい) Things I kept safe by keeping them locked (鍵をかけたまま守れたもの) Things I saw because I opened the door (鍵を開けたから見えたもの) I don't need an answer (答えなんてなくてもいい) [Outro] The lights were back on at home (家に明かりがもどってた) I opened the front door (玄関を開けて) And I asked (聞いてみたんだ) “Was the door unlocked?” (「鍵、開いてた?」) “No, it was locked.” (「ちゃんと閉まってたよ」) “…Really?” (「……本当?」)
