HIMYM: Barney Stinson... but with a Vampire System?!

One night, while on his regular hunting routine, Barney suddenly becomes the hunted... Watch how Barney, the biggest, most Legendary womanizer Amongst mortals, Becomes the ultimate Vampire! This is the true meaning of The Possimpible! (reference to s4 not a typo) this fanfic is only gonna follow some of the tv episodes, updates will not be consistent ,that is unless i see special interest in it...I write this for fun, not gonna entertain toxic people... The target of this fanfic is gonna be a Harem. And there isn't going to be any NTR. I read and take every one of your comments and requests into consideration but I'll make this clear, this is my fic, you want to drop it cause you don't like something, fine by me. I get nothing even if you don't. I don't write this for money or whatever other reason you can think of, but to pass my time in a slightly better way. If it starts being more of a bother, I'm just gonna stop writing and that's it. Hope you enjoy reading it, If you don't, well, all I can probably say is don't ruin it for others... Disclaimer, i don't own the characters and the original plot.
