The whole world is out to kill me.But if they think I'm going down that easily, they're in for a surprise. Using my game knowledge, I'll dodge every death flag, exploit every loophole, and rise to the top! And hey, if I end up with a harem of gorgeous girls along the way? Well… let’s call it a happy bonus!This is my story—where I rewrite my destiny, break the game, and maybe... just maybe... finally get that kiss!Support this Shameless Author with Power Stones Gifts and Golden Tickets
