He Shixu was hit by a car on his way to report a crime. When he opened his eyes again, he wasn't in a hospital but in an unfamiliar place. He had no phone or ID, making him an undocumented nobody who didn't even dare call the police.
After spending two days sleeping on the street, he called his nemesis, Wei Jin, with an attitude of giving up on everything. The moment the call connected, He Shixu shouted at him to come get him.
The instant he saw Wei Jin, tears streamed down his face. "Wei Jin, hurry and save me."
Wei Jin said, "You hate me so much. Why should I save you?"
He Shixu said, "No, no, I don't! I've always looked up to you as a role model, Wei Jin. I'm begging you."
After freeloading at Wei Jin's place for several days, He Shixu decided he couldn't keep living like this and had to go find a job.
He Shixu asked, "Wei Jin, can you help me get an ID? I can't keep freeloading forever."
Wei Jin said, "You can if you marry me."
He Shixu said, "How can two men get married?"
Wei Jin said, "Looks like you know nothing about this world."
After cramming on the genders in this world, He Shixu was utterly shocked. At least he was a Beta, not some Alpha, Omega, Sigma, or whatever. He was basically a normal person.
To get an ID, he had no choice but to swallow his pride and marry his former nemesis, Wei Jin. He planned to ask for a divorce once he was settled.
Then came his second differentiation. He Shixu touched the back of his neck, which had nearly been bitten to shreds. His lower belly was sore and swollen, and he had no idea how much he'd been filled with. He could barely straighten his back.
Wei Jin narrowed his eyes and rubbed his cheek against He Shixu's. "After a permanent mark, as long as I don't commit some serious wrongdoing, we can never get divorced for the rest of our lives."
He Shixu lay limp on the bed. He couldn't have imagined that someone who'd been calling him brother just two days ago would bend him over today.
