Okay, I had a look at the first few chapters.
First of all, I really liked the title of your story, it was eye catching and got me interested as a reader. Your start in general and the story (if it's heading to where I think it is) is good. I particuarly liked the first paragraph about Love poison and hate - this one convinced me about your writing - really good!!
But, there are a few things you should work on. Some spelling mistakes (too vs. to, etc).
Now to the important stuff. When you start your story you have to draw the reader in, right from the beginning. You have to try to write it in such a way that he/she can't stop reading. You started with her first encounter with Damien, which is good, but, for instance, I wouldn't give the reader all the information about the main character right in the beginning. You could add information somewhere during the story - someone commenting about her hair, or the fact that she's so slender. It's far more interesting if we learn it somewhere along the way, than her giving us a full description.
I haven't read far enough to make judgement on the characters, but I think there are some things you could work on. I'm sure there is a reason why Mr. Page is calling her beautiful and switched classes for her. BUT: I would tone it down a bit. I have to be honest, I couldn't imagine any teacher, no matter how cool and easygoing, to be so straightforward (Unless I misunderstood the situation). Also think about her reaction when he tells her he switched classes for her. I know I haven't read further and don't know much about their relationship (only teacher-student?), but I would have expected her to be shocked... Work on the characters, try to think how each of them was shaped by their past, by who they are. All that will define how they react to things.
All in all I think you're headed in the right direction when it comes to writing. Keep on writing, I think you have talent! I'm sure you'll be fine!
