I married my arch-nemesis and ended up falling for him

Originally, I was just a regular Beta living in an ABO world. But during a fight with my lifelong rival, I unexpectedly presented as an Omega. I collapsed right into my rival’s arms.

To make matters worse, Lin Zeyan leaned in and sniffed the back of my neck.

“Hey, why does your scent smell so good?”

Seriously, I’ve never wanted to punch someone so badly in my life.
