Su Xi and Xie Linhuan were bitter rivals who fought tooth and nail in the real world. They entered a quick transmigration romance System one after the other.
In the first world, both remembered everything, and they immediately started pulling each other's hair. Su Xi set out to win over the campus heartthrob, while Xie Linhuan did everything he could to sabotage her. She sent a love letter, and he intercepted it. She arranged to see the heartthrob at the movies, and he bought out every seat. Just as she was finally about to hold his hand, Xie Linhuan burst out of the bushes shouting, "The teacher's coming!" Su Xi chased him around for the entire world, turning a sweet campus romance into an all-out brawl.
When the mission was evaluated, the System announced: [Romance progress: 0%. Hatred level: 9999+. Hidden title acquired: Destined to Die Alone]
Su Xi declared on the spot, "Just you wait in the next world!"
But something went wrong as soon as the second world began. The transfer tunnel collapsed, and Su Xi was swept into a spatial rift. Xie Linhuan rushed over and shoved her out, but was swallowed up himself.
His final expression was still that same infuriating grin. "Su Xi, you owe me your life. Don't forget to pay me back."
Su Xi went charging into the subsequent worlds to find him, only to be left completely floored by the Xie Linhuan she found.
He'd lost his memory and didn't recognize her. Worse, in every world, he had become the target she needed to win over and save.
And so Su Xi began the long journey of "saving that bastard." She kept saying that the first thing she'd do when the idiot woke up was beat him to death, but she took lightning strikes for him, faced assassins for him, and even shielded him from ghosts, scaring herself into tears.
When she finally managed to wake him up, Xie Linhuan was silent for three seconds, then asked:
"So you admit you like me?"
"...I'll beat you to death."
