  ただありがとう伝えたくて　ただ君の笑顔を見たくて
  もう振り向かないよ　瞳の先へ
  今幸せを伝えたくて　大切な人が誰かってね
  ありがとう　君と出会えて
  この全ての覚えたこと　それはいつも it's hard for me
  でも何度もつまずいて
  それでも今ここにいるのは描いていたから
  いつかきっと信じていたのさ
  Everything we know 繋がるよ今
  ただありがとう伝えたくて　ただ君の笑顔を見たくて
  もう振り向かないよ　瞳の先へ
  まだうまく伝えられなくて　大切な人が誰かってね
  ありがとう　君と出会えて
  真夜中空見上げ　not knowing
  震える　怯える　揺れる not showing
  その上どうしようもない
  不安で眠れない
  かすかな声で叫ぶんだ
  さようなら涙の日々よ
  Your heart and soul is in it, feel it
  昨日と違う明日にするよ
  Make a brighter day
  もしもずっとそばにいてくれたら
  Everything we know 始まるよ今
  その君のあふれる笑顔が悲しみを優しさに変えて
  もう振り向かないよ　瞳の先へ
  この幸せを伝えたくて　大切な人が君だってね
  ありがとう君と出会えて
  手と手をつないで yeah
  いつか話した夢の続きを叶えよう
  I'll be ready
  ただありがとう伝えたくて　ただ君の笑顔を見たくて
  もう振り向かないよ　瞳の先へ
  今幸せを伝えたくて　大切な人が誰かってね
  ありがとう　君と出会えて

• Translation
  Just want to say thank you, just want to see your smiling face
  Already can't turn away, standing in front of my eyes
  Want to tell you my happiness right now, and who is important for me at the moment
  Thank you for ever meeting you
  Trying to remember everything that's happening now, is hard
  But no matter how many time I've stumble
  I'll be the one here that describe it to you
  I'll always be there for you
  Right now everything we know will tie together
  Just want to say thank you, just want to see your smiling face
  Already can't turn away, standing in front of my eyes
  Want to tell you my happiness right now, and who is important for me at the moment
  Thank you for ever meeting you
  Looking up at the midnight sky not knowing
  Shivering Swaying to nightmare of not knowing
  Other than that I don't know what to do
  Can't fall asleep because of this anxiety
  Calling faintly to you
  Everyday crying good bye tears
  Your heart and soul is in it, feel it
  Make tomorrow different from yesterday
  Make a brighter day
  If you are to be by my side forever
  Everything we know now will begin
  Your smiling face flood away sadness with kindness
  Already can't turn away, standing in front of my eyes
  Want to tell you my happiness right now, and who is important for me at the moment
  Thank you for ever meeting you
  Hand to hand together yeah
  Let's continue to wish about how someday dreams that we talked about will come true.
  I'll be ready
  Just want to say thank you, just want to see your smiling face
  Already can't turn away, standing in front of my eyes
  Want to tell you my happiness right now, and who is important for me at the moment
  Thank you for ever meeting you

All everything is hard at the first time. But, soon or later, you'll know its easy. Make a good habit to live without your girlfriend or boyfriend. Like this song, just want to say thank you.
I don't talk about break up. For me this song about: how you move on, go forward and never see your backward. Maybe now you fall down, but you must believe that you have another chance to get your dream. Agree?
