Also known as: "Bro, I'm a guy. I really can't get pregnant," "Bro, I was wrong. I won't run away again," "Please spare my ass 😭😭😭," and "Hehe, I have to survive no matter what."
I've fallen from grace: I went from being the only young master of a famous conglomerate in City A to a fake heir.
If you ask me what I regret, it's ordering takeout on a rainy day.
It was pouring that day. I shouldn't have ordered food just to experience what it was like, and I shouldn't have called the delivery rider back to confront him after someone stole my order.
Beneath the sheets of rain, I saw the rider's face. He looked exactly like my mom!
Before I could even process it, my parents, who were home for only one day out of 365, came rushing over like rockets and hugged the rider, crying and calling him their precious baby.
And just like that, within a single day, I went from the real heir to the fake heir, while also becoming the real heir's designated future wife.
I lost my inheritance, and I'm about to lose my ass.
But that wasn't even the worst part. After my parents revealed the real heir's background, the supernatural resurgence began.
The world fell into chaos. Monsters ran rampant, and four evil gods debuted as a group. Worship the evil gods and gain eternal life. Everyone rushed to worship them, except me.
That's when things started getting weird. My parents, who had left me to my own devices, began constantly urging me to have a child and give the real heir a son. I wanted to pull out my style and prove that I was a man.
And the real heir seemed to start believing I could get pregnant.
I was desperate and helpless. To protect my ass, I entered an evil god's church and worshipped all four evil gods at once.
Then the real heir went crazy. It wasn't like I'd worshipped four evil gods. It was like I'd put four pairs of horns on his head.
My ass is gone, my freedom is gone, my belly is swelling, and I'm locked up at both ends.
He says if he finds out anyone has touched me, I'm done for.
...I'm done for.
Not first person; the main story is told in third person. Slight Lovecraftian horror, all kinds of bedroom games, possibly a nonhuman love interest, tentacles?
1v1, both are virgins
A goofy fake heir with a bizarre way of thinking as the bottom x a monstrous real heir as the top
