I really don't know.... It was a manga were one boy started to date(or did just go out) with a girl that just turned out to be a vampire( or something like that). The girl tryied to eat(or suck his blood, i don't know, my head is already hurting) but for some reason that i don't know it didnt work out... A accident i think. Well, anyway, the girl dies and the boy survives with one tranplant with organs of the vampire girl. And something changes in him... Somebody knows this or am i just crazy? Sorry for the bad english.
