My Boyfriend​ is a​ Vampire

Being beautiful is never easy, especially if you're an eighteen year old boy like Gene who is constantly mistaken for a girl because of his delicate good looks. Gene is, in fact, anything but delicate. He is the ringleader of a group of tough kids in an all boy's school, and he's quick to beat the living daylights out of anyone who even hints that he resembles a girl.

If that wasn't hard enough for a regular teenage guy to cope with, his life is about to take a shocking turn for the worse. When Gene stumbles upon strange happenings in the forest, he gets sucked into a world of vampire intrigue and sinister romance that he never knew existed. And he learns that there are worse things than being turned into a vampire: being turned into a girl?!
