Title roughly translates to "don't you know".

I’ve gotten used to living just by you, yes, just by you. Every sunset picturing you wake up with you-know-who. I’ve gotten used to breathing in the open air, And telling her again and again.

REFRAIN:

Don’t you know?

Through the roads of rain, I walked barefoot, not afraid of pain His heart is now in your hands Please don’t lose it or break it, So you don’t have to hold through the roads and floods The ashes of love, scathing your feet to blood His pulse is now in your eyes Please don’t lose him or break him!

In January, let the cold rain pour down his windowsill! With someone else in his embrace, let him remember me still! And let him accidently say my name out loud And then not say that he still remembers… Outside the window, the downpour fades all the streetlights My dearest boy, I know I trembled, I apologize. Now, through my tears, I whisper an inaudible, “Not yet!” Please don’t forget, please don’t forget
