There were a few things that I think needed a little help.
1.
What if they were older? Satu realized that she had been playing a lengthy game of “what ifs”.
The article of a tabloid had set up so many questions in her mind! Tabloids are to be disregarded as about as real as…fairy tales!
You changed tenses halfway through this bit. Fix that, and it's fine.
2.
Her dreams filled with everything except what she wanted to dream about – fairy tales. Then again, some fairy tales continue living unknown from when they were lost by a generation. Satu may have very well been dreaming about fairy tales.
There's something about this bit that seems a little weird. I can't quite put my finger on what it is, but the last sentence almost seems like you changed view points or something. It just seems a little awkward.
3.
After kicking on her shoes, Satu slid the glass basement door open and closed it behind her.
Kicking on her shoes? Maybe people say that and I just don't realize it, but it sounds a little weird. How do you kick on your shoes?
4.
Satu trudged along, staring at her feet to avoid the gazes of homeless or drunken shadows that draped on and over benches.
That last bit (the bit in bold) seemed a little weird to me. I know what you meant now, but when I first read it, I was thinking "What the heck?". I think rewording it might be a good idea.
5.
A string of curses came from a female voice as Satu’s companion-through-clumsiness began to stir from the collision.
There's nothing wrong with this, I just like the idea of a "companion-through-clumsiness".
I liked this piece. It's well written, and it got my curiosity up. Can't wait for the next bit!
Keep writing!
