I haven't managed to come up with a blurb yet, so here's a rough outline for now.
The bottom is a would-be invincible hero, but he's still at the "Don't look down on a poor young man" stage. He knows he'll become an invincible hero someday, but then he suddenly gets pregnant, and can't terminate it. He has no idea who the father is.
So he gets angry and starts looking for the culprit.
There are four suspects:
His boss at the company where he interns, a mature, fatherly top with a strong desire to control.
A famous singer. I haven't figured out this character yet.
His handsome roommate, a cold, aloof type.
A classmate, a cool-guy type who's not much of a student. He's secretly the owner of a sex toy shop. Actually, his parents own it, and he only helps out occasionally. He finds it embarrassing, but after meeting the baby, he suddenly realizes how useful the shop is (...)
The bottom's invincible-hero identity is something he made up. After reading a novel, he got into a car accident and suffered brain damage, so he thinks the book is about him. In reality, he's a vicious cannon-fodder character, a lot like the little sheep next door.
He's a country bumpkin from a remote mountain village who got into the lowest-ranked major at a prestigious university in a big city, and came last in the entrance exam. He can't stand anyone and hopes all those privileged heirs will fall into a cesspit. In the end, every darling of heaven bows their head to him.
All the tops are inexperienced. They all compete to be the baby's father, and there are kissing scenes with all of them, along with other kinky play. There may even be some grinding, but he only actually has sex with the official love interest.
I set it up this way because the bottom is pregnant, so they can't have sex. Besides, I'm a die-hard 1v1 true-love author, just occasionally wicked, so I still want to leave a little bit of pure romance for the official top.
The bottom gets together with the official top before giving birth. When the time comes, all the tops show up. They're mainly worried, but also secretly wondering whether, if the baby turns out to be theirs, they'll still have one last chance to win the bottom over.
The bottom is curious about who the father is too, and wants a paternity test after the birth. The official top stops him and refuses to let him do it, saying, "No matter whose child it is, it's mine," then kneels by the bottom's bed and cries.
He's terrified the baby won't be his and someone else will steal his wife away (...)
Each top will love only the bottom for the rest of his life. The bottom has a child with the top, gets married after graduation, and the other tops keep waiting in the wings in case they get divorced.
P.S. The baby's father is the official husband.
Before discovering he was pregnant, the bottom didn't know or wasn't close to any of the tops. He was penetrated, but for various reasons, he doesn't know it himself.
