What did I really lose on that day? I forgot long ago We lost sight of each other in the twilight What's more; we were unable to return Somewhere our brittle, broken hearts Try to hide behind strong words Try to hide Farewell, although we couldn't be together We will carry on Even in a world where you no longer exist, I will run Overcome… Overcome
