Dammit

That's the detective, so yep.
- Silver haired boy's parents are dead (mother murdered, dad on the run and presumed dead)
- Silver haired boy was found by the detective, thus begins the light and dark metaphor.
- Detective takes a shine to the silver haired boy, get's him to write his name, makes him food etc. Silver haired boy secures a place in an orphanage. Detective takes some time off work to meet the silver haired boy when he graduates secondary school.
- Then as you see, both are devoted to each other.
- Both characters are willing to commit crimes in order to save one another, keep each other's attention. The silver haired guy wants his light amid darkness (an official translation should hopefully clear things up) and presumably uses this as motivation for the murders. The silver haired guy is framed, and caught whilst taking a purple haired woman (he though) to his murder room. The detective gets upset that his baby angel has been caught for murder and tries to presumably frame the pink haired vampire. In the last chapter (raw) we see the detective creeping up on the pink haired guy and aiming for his neck with some sort of weapon.
(That's all I can remember without re-reading the raws again).

ohhhhhh yea the little saddistic dude that was torturing that man
