Answer for...dear「A」

Japanese:

もう二度と会えないけど今はずっと君の幸せ願うよ
最後の夜に交わした約束はずっと忘れないで

壊れた歯車時に迷い気付けば涙を流してたね
思いは届かず離れていく夢と違う未来だけを残したまま…

眠れない夜を越えて今は二人強く生きていかなくちゃ
君が残した言葉の意味だけをずっと求めたまま…

English:

We will never meet again, so I wish you all luck
Our promises we made the last night, never forget them

The destroyed gears made me roam in time, when I realized I started to cry.
Without any feelings we separate, we left for a future without our dream

We have to bear through nights we can't sleep, we must be strong.
I will always seek for the meaning of the last words you left me...
