[IT'S NETORI, not the disgusting Netorare]COUGH Since our lazy author-nim is a bit... let's say, challenged in the synopsis-writing department, I'm stepping in. Sigh... now he's making me do his job too... X(Let's hope he can at least complete my story.Anyway, I'm Lucian, a 35-year-old guy with a rare disease that's cutting my time short. But here I am, working till my last breath sigh.*KNOCK*Oh, a guest! Gotta be quick—can't keep a lady waiting. So, after I kicked the bucket, I woke up in a body that kinda looked like mine but not really. Turns out, I'm on a flipped planet ruled by women. And guess what? I'm married to a cold and crazy ya#SPOILER#. My new mom? Total #SPOILER#. Then I *CENSORED* her right in *BEEP* of my new dad.To get stronger, I need to travel to #SPOILER#. Instead of a cool system, I got a useless b... *BANG* (gunshot).Due to health related issues, Lucian will be taking off, and the author will continue from here...“Kyaaa!! The patient died from a gunshot!”Don’t worry, Doc. He was on borrowed time anyway. So, let’s talk about what this story has.“B-But, he still had a few months to—”*BANG*So, here's what you can expect: Revenge, mystery, a bit of comedy, an overpowered MC (maybe), all the deredere, milfs a lot of them, wince... *COUGH*, hacking, a hero, a villain, manipulation, crime and a lot more.What you won’t find here: NTR, Yuri, a girlfriend, a job?, etc.Now, the serious stuff. This story aims to keep things light and happy but will have its fair share of sad and rage moments. Alright, that's it for now; I need to go, or we might actually lose our MC before the story even starts...For those who prefer to keep things PG, feel free to skip the R-18 chapters. We understand, really! And for those who pride themselves on being ‘Men of Culture,’ get ready to savor the spice. Bon appétit!
