How Could My Nemesis Become My Wife? [ABO]

Fu Buwei had a rival who was every bit his match: Jiang Han.

Jiang Han was just like his name, cold as frost, a gleaming blade in the Empire Academy's arsenal.

Fu Buwei's year-after-year undefeated top ranking began to waver when he met Jiang Han. But he was eager to fight, constantly competing with Jiang Han. The two were entangled from their first year all the way to graduation.

He thought they'd spend their whole lives fighting endlessly as rivals. Then, in the year after graduation, Fu Buwei received news of Jiang Han's death. The Empire's peerless, shining blade had fallen, for reasons unknown.

Fu Buwei was shocked.

Fu Buwei couldn't believe it.

Fu Buwei had no choice but to accept reality.

On the first day without Jiang Han, Fu Buwei felt empty.

On the second day without Jiang Han, Fu Buwei felt lonely.

On the third day without Jiang Han, Fu Buwei was dazed and distracted.

He thought the rest of his life would remain so dull and empty. Then, during a mission to hunt down space pirates, Fu Buwei had an accident. When he opened his eyes again, he'd returned to ten years earlier.

Ten years earlier...

Fu Buwei perked up. He immediately went looking for Jiang Han, his rival, whom he hadn't seen in three years after they'd broken their promise to meet.

He'd imagined Jiang Han would come from a distinguished family like he did, with access to countless resources. Then he saw a half-grown boy curled up on a street in a poor planet, barely clinging to life.

Fu Buwei: "...?"

This wasn't what he'd imagined.

For the sake of their future eternal rivalry, Fu Buwei brought the gravely ill Jiang Han back with him. He treated his wounds, gave him books, gave him clothes, and gave him everything he should have had.

This time, he would personally raise his rival.

Fu Buwei waited and waited until Jiang Han finally turned eighteen. But that night, Jiang Han, who was supposed to be an Alpha, abruptly differentiated into an Omega right in front of him.

Fu Buwei: "?"

And then Jiang Han ended up in Fu Buwei's bed.

Fu Buwei: "??"

The Empire's once ice-cold blade knelt before him like a rose waiting to bloom.

Fu Buwei: "???"

Wait...

A rival is a rival.

How could a rival become your wife?
