Characters

When a new girl arrives at the school and causes some memories to form in a young mans mind, he starts to change. She seems similar, but different than who he remembers. He swore he would protect her at all costs, but will he do the same for the new girl look-alike? Is she a rebirth of her or just merely someone who looks and acts like her? How will this affect him, and can she save him from the past that haunts him? Or will it continue to eat away at him until he loses control?
