[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!

Yuan Jia died early, and only after meeting the system did he know that his younger brother was the male lead, and he was the male lead’s cannon fodder brother.
Even if he is more talented than the male protagonist, how can he be more powerful than the male protagonist as a supporting role?
So he suffered a plot kill.
His business empire will be inherited by the male protagonist’s younger brother…
The connections he made will be inherited by the male protagonist’s younger brother…
The marriage date he set was inherited by the male protagonist’s younger brother…
And he is just the older brother who died young in the memory of the male protagonist. Take it out and remember it when you need it, and forget it when you don’t need it.​​
Yuan Jia’s goal is to work hard to live longer than the male protagonist’s younger brother.
As long as he doesn’t die, the male protagonist will always be just a younger brother.
