As a silver-rank agent in the Space-Time Administration, alpha Ling Shui'er breezes through S+ missions.
Since her debut, she's been unstoppable and has never lost.
Unfortunately, the same is true of her "archenemy," Xiao Sesese.
In fact, Xiao Sesese completes missions faster, more ruthlessly, and more accurately than she does.
That's why no matter how hard Ling Shui'er tries, she can only remain a silver-rank agent, forever in second place.
Then one day, Xiao Sesese suddenly failed a mission and was sentenced to humanely destroy herself. Her body shattered into fragments that scattered across the three thousand worlds.
While regretting the loss of such a formidable rival, Ling Shui'er happily took her seat on the throne of a gold-rank agent.
Unfortunately, she hadn't been sitting on it for long when a new S+++ mission came down.
Ling Shui'er had to travel to the three thousand worlds and find Xiao Sesese's body fragments, or the Space-Time Administration would face its greatest crisis ever!
SOS!
As if carrying out an S+++ mission weren't enough, she also had to bring back the "archenemy" who posed the fiercest competition for honors! Ling Shui'er flatly refused.
But her protest was ignored.
In the end, Ling Shui'er still had to go looking for Xiao Sesese.
Ling Shui'er had always thought her "archenemy" was an invincible, terrifying she-demon.
But after Ling Shui'er entered Xiao Sesese's inner world, she discovered that the version of herself in Xiao Sesese's heart was a weak, pitiful, helpless omega girl who desperately needed saving by Ling Shui'er, a scumbag alpha.
The most awkward part was that the mission could only be completed by consummating their relationship...
Ling Shui'er could only say, "Come on! I'm not a scumbag!"
Ling Shui'er really wanted to explain to Xiao Sesese that, when she was in her right mind, the two of them were enemies.
But Xiao Sesese had eyes only for her.
Xiao Sesese's gaze was tender. "Shui'er, I'm all yours."
Ling Shui'er hesitated. After a long struggle, she swallowed the explanation she'd been about to give and finally managed to say seven words: "I'll take responsibility for you."
One lifetime of love, one lifetime of responsibility; three thousand lifetimes of love, three thousand lifetimes of responsibility.
