Ok i really really liked the plot of this manga. There was very little humor, plenty of fighting and drama + mystery of the past for the girl. I've read up to volume 5 which i think is the ending because they haven't updated the manga since 2010..
If it was the ending, it kinda sucked because you had the boy saving the girl, surviving his injuries and then it shows how the boy's best friend was reminiscing how he had come upon this same girl in the past while he was trying to commit suicide and his being there saved her from being raped and then after his recollection he returns his focus to the present and is nearly hit by a car, but he gets out of the way..and as he is thinking how happy he is to have lived he actually gets hit by another car....then it shows them going to his funeral......very very corny...
