1. Girl-on-boy, female Alpha Yu Taixuan and male Omega Deng Chi. Happy ending.
2. The setting is original.
When Yu Taixuan first met Deng Chi, she was dressed in combat gear and lying on an abandoned mine on a trash planet, her whole body covered in blood and mine dust.
Deng Chi had twelve guards with him. Looking at Yu Taixuan, who was barely clinging to life, he had a delicate, innocent appearance, but his eyes were cold and merciless.
"If I save you, how will you repay me?" he asked.
Yu Taixuan's starry eyes settled on his face. Her answer came smoothly: "Of course, I'll be your personal guard and protect you, beautiful one."
So Deng Chi saved her, and once she recovered, Yu Taixuan became his thirteenth guard.
Deng Chi was as beautiful as a fresh lotus, radiant and dewy, the most beautiful person in the Federation.
He was the illegitimate son of the Speaker of the Federation's Capital Star. After the Speaker's legitimate eldest son seized power, he used assassins from Death Star to slaughter Deng Chi's entire family.
Deng Chi was the only survivor, and his pursuers came one after another.
The thirteen guards at his side died in succession. In the end, Yu Taixuan was the only one left.
"You should go." He clutched his injured chest, suddenly feeling a pang of conscience. He didn't want her to be dragged into this and die.
Yu Taixuan wrapped her arms around him. As she leaned closer, her lips seemed to brush his delicate forehead by accident. "I forgot to tell you. I'm from Death Star, and I used to be its strongest weapon: Nightglow."

Deng Chi had no qualms about using others.
If using someone could help him achieve his goals, he would do it without hesitation.
Yu Taixuan was no exception.
Deng Chi pressed a dagger to Yu Taixuan's chest. His eyes reddened as he asked, "Was the Death Star assassin who killed my whole family you?"
Yu Taixuan looked at the man before her and gripped the blade with both hands. Blood ran from the wounds in her palms onto her bright red battle robe, its vivid color startling.
A trace of self-mockery rose in her eyes as she gazed at the partner she'd accidentally fallen in love with for real.
"It was me. It was always me," she replied.

Many years later, after suffering one defeat after another, the Federation sent an envoy to the Empire to sue for peace and deliver a letter of surrender.
The Empire's strongest war god, Yu Taixuan, tore it to shreds.
The bloody wound in her palm was shocking to behold. Gazing at the elegant lotus flowers in the garden, she said to the envoy:
"I've heard the young master of the Deng family in the Federation is famed as a flawless jade. If the Federation sends him here for a political marriage, perhaps he alone could turn back an army..."
