Hugo Fernandez, a short, skinny virgin with zero charm, was a young man with grand dreams. He had just started college and was brimming with hope for a bright future, but a rather unfortunate food poisoning ’incident’ soon turned his life from bad to worse. He experienced a social death! Out of the blue, a mysterious girl’s voice echoed in his head: [Ding! Fate has aligned, and your woeful destiny with women has reached the heavens! You have been granted the Ultimate Harem System!!!] Hugo’s listless eyes widened. Had he finally received his own cheat code? Was it time for him to ascend to the heavens in a single leap and start attracting women left and right? The mysterious voice spoke again: [Ding! Initialising Death mission... Seduce a 7+ woman within one month or die!] Hugo blinked, his jaw dropping. “Wait, what? Seduce a 7+ woman or die? What kind of medieval torture is this?
