okaaaay...xD
So basically this is a short Japanese version of Vampire Diaries.
It revolves around 4 teenage vampires, they all live in a house together under the protection of there "guardian".
One of them is a newbie who has suffered from a traumatic past.. and the others help him through it.
Let me make one thing clear... don't go watch this with the hopes of bromance... ITS NOT.. it deals with brotherhood and family.
Personally I would recommend it, no spoilers but just so you can be comforted it does have a happy ending.
