Kanekai Vivien is a gothic, fullblood vampire, living in a large manor in London. Usagi Moyin is the son of a famous vampire hunter. Two completely different lives are suddenly crossed when Usagi moves to London looking for work, after losing his memory - courtesy of a vampire attack on his family, which turned him into a half-blood. Can these two boys spark a secret romance? Or is Usagi's past going to catch up to them all too quickly?
