''HANABI episode II'' translation and romaji

[masa]

I've tried to translate the shortest lyrics first. If you find some unnatural words, please inform me.
-------------------------------------------------------------

The summer has come again and again since then
But why am I looking back upon the past again
Tracing the footprints?

I remember everything even now
Your voice calling my name, your casual habits
I want to forget, and I don't want to forget

Did I choose the right way?
But I keenly understand there is no answer
Whomever I may ask it to

Please tell me some day that you are happy
And smile

I gently lock the memories away
Leaving them to be beautiful

This feeling, this feeling, go up into the sky
And be dispersed beautifully like a firework
