hmmm....
you have a very interesting start for a story here.
I like that you seem to be branching away from writing a "My Chem" fan fiction, rather, actually creating characters that are simply resembling the members.
I'm definitely interested to find out what has caused Frank to become so timid, so terrified of the people, and seemingly in particular, males around him. I think I'm in agreement with the idea of some sort of abusive home...perhaps his father? step father?
Um... critique.
I would space out your paragraphs, it makes it easier for the readers and allows for easier story flow and reading.
Be careful of grammar and punctuation as well.
As I said, you have a great start here and I'm interested to see where you take it. :)
Update soon!
Cheers
