How does a little flame work?

Adrian is a typical teenager living in a boarding school. He believes that his life sucks, cause of all the bad luck in friends and grades that he's been having. So he relieves himself in his daydreams. The most common character in his daydreams is Detrië, a fire wielding specialist. Though Detrië's adventures reflect on the actions and people Adrian comes in contact with, Detrië doesn't know that his existence is a fake.
But how will this especially bad day work out for Adrian and Detrië?
