Well, here's my own interpretation of a more stylistically sounding English version...

*I can’t go back, I won’t go back, there’s nowhere left for me to return
However much I look behind me, I can not change my footprints
And even if I paint over them beautifully
My mind won’t be deceived*

(Don’t look back) The unattractive
(Don’t look back) parts of myself are dear to me

*repeat

(Don’t look back) I can smile
(Don’t look back) Because that period is over

**I want to go forward, I can’t go forward
Hesitating like this means that I won’t hesitate anymore
It would be easier for me to stay here
But nothing would excite me**

What fulfils everyone is the period in their lives when they shone the most
How tragic that is…

Don’t look back

**repeat**
*repeat*

The curtain falls in this way
And you…?

Don't look back
