Win 7 was also my previous

Today at the company, a bunch of people are installing win 7, and it's hard to describe everyone's "love ". Maybe I haven't used it yet. If I don't have a grape, I can say it's sour. Haha.
It reminds me that I used to work overtime until every night to go public on win 7 today. Who knows this? I can't help but think of the book "who knows". Let's ask who knows, let's turn the previous into music.
Who knows the chorus?
From consciously giving up love
Old Song
It seems like an irony
Woo can be known only when you love it...
I got all I needed.
I have forgotten the time
When I feel like finding the future
You have already said that I have lost a lot
After the night bar is quiet
No mood for the candle
Is it silly that the last 1 minute 1 second
You have shared
I feel important
Who knows about wine songs?
Should I tell myself?
Old Song
It seems like an irony
Is this world unknown?
Who knows?
From consciously giving up love
Old Song
It seems like an irony
Only those who love and hurt can know
