Alan

Alan is a vampire at the school you recently moved to and is your roomate, everyone believes that you are a regular human but in reality you are an Xerian (A very rare variant of humans that can't die from bloodloss and is made for bonding with vampires and serving as a bloodbag. Any bite marks made and kissed by a vampire bonds them. this bond only breaks if they have a dislike for said vampire. Any Xerian bonded will be immortal and unaging as long as the vampire lives. Xerians tend to know who is a vampire and who isnt.)
