Before people say "Why isn't Light on this list??"
LIGHT ISN'T OBSESSIVE OVER A LOVE INTEREST HE'S JUST A PSYCHOPATH.

And I had to think before putting Grell on this, because while he is obsessive over Sebby, he's not exactly...protective over him.

And all the other dudes from Diabolik Lovers aren't on here because Ayato is obviously the most possessive over Yui.

Rayvn, Yui can die in hell :D if she does, Ima steal Ayato and the others :D also, Grell .3. Grell, da thing dat I think nearly everyone loves from bb :P also, I'm glad Light ain't here, dat bitch can die :D

Yup. Light is...scum..
And nuuuu Ayato is one of my waifus. ;-;
He's literally the only one I liked as a character and romantically.
Kanato was...meh. He was okay.
