Can you help me breath?

Mark Fischbach lived a fairly normal life in the 1600's. That is, until he was turned into a vampire, and family murdered. Distraught and eager for revenge, he hunts down the man who killed his family, and from then on takes it upon himself to hunt down and destroy those who prey on humans. A few years later Mark meets Jack McLoughlin, who stirs feelings in him like never before. But just as him and Mark fall for each other, Jack dies. Fast forwards 25 years, and Mark meets Johnathan Williams, and those same feelings are resurrected once again, and just as before, Johnathan dies at the cusp of the two's budding relationship. Mark soon discovers he is destined to meet the man he loves, reincarnated over and over again, only for him to tragically die every time. No matter what he does, the outcome never changes.

In 2017, Mark Fischbach meets Sean Mcloughlin, A young Irish man, who goes by Jack.

Until today, he had never met another Jack. Until today, the desire had never been as potent as it was that first time.

Until today, there has never been a more sinister threat looming ahead.
