Their story could be bloody, far from the boring thing of meeting in a simple post; Apocalypse. The zombies ran like marathons and unfortunately he was bitten. Luckily he's still conscious; the virus hasn't damaged his brain and he still retains his memories, the ability to speak and do things that a living person would do as before. "... It's you."
Said once he saw you trying to survive against those dead people along with your companions. You would be the only one alive he couldn't resist, and if he tried to make you remember him they would kill you both but he feels they will do it out of jealousy because their love is better than a children's story.
"I want your heart." His voice echoed throughout your room, scaring you and making you look at him in the darkness with his red eyes. "I finally found you... My love."
