I get reborn, this time bound to a simp system. In my previous life, when the apocalypse happened during Christmas Eve, I gave Victoria Blake, a beautiful woman, shelter and respite, only for her to backstab me in the end. Apparently, she had revealed my home's location to a scion named Tristan Cole when I wasn't paying attention. Not only did those bastards take over my shelter, but they also tossed me to the zombie horde. When Tristan asked Victoria if she felt guilty, she just reclined in his arms while tittering daintily. "That's just one of the lapdogs I've reared. If he's dead, then so be it." Now that I'm given a second chance at life, I'll make sure to repay them for the pain and hurt they've caused me in my previous life.
