An old idea I had, putting it up here for now
After being bound to the Protagonist Growth System, Xin Ci was sent to a future world controlled by corporations and the Federation.
In this world, the protagonists belong to the Federation faction. They are destined to destroy the corporation's conspiracy and save the world.
System: Your mission is to ensure the protagonist's safety at critical moments and help the protagonist team complete the main storyline of destroying the corporation's conspiracy.
Xin Ci: Got it. I'm a walking cheat code.
System: However, due to an error in the space-time transfer, you are currently seven years before the main storyline begins. The System is low on energy and is about to enter hibernation. It will reactivate in seven years. Host, please do your best to survive until the main storyline begins.
After the System went into hibernation, Xin Ci felt he couldn't waste these seven years, so he decided to let loose.
Two years after graduating, Xin Ci had successfully transformed himself from the finest graduate in the history of the military academy into a traitor hated by everyone and abandoned by all.
His friends' confusion, his classmates' loathing, his childhood friend's break with him, his closest friends leaving one by one, and the fearful, disgusted looks of those around him: none of it could stop Xin Ci from using the corporation's power to climb higher and higher, until he became the Federation military's head interrogator, a brutal and ruthless man whose name struck fear into criminals.
He was the corporation's most loyal attack dog, its spy in the military, and its public face.
His methods and loyalty eventually caught the attention of "that person," the head of an organization few had ever seen in person, someone who existed only in rumors and the words of powerful officials.
From then on, Xin Ci took on one more duty. He was not only the organization's loyal henchman, but also the lover of the unseen leader who ruled the Central City with an iron fist.
A year later, during a mission, Xin Ci pointed his weapon at the leader he had sworn loyalty to. While his colleagues watched in shock, Xin Ci calmly called in the Federation police he had arranged to lie in wait at the mission site, carrying out the arrest, then shot the leader without hesitation.
Three years after graduation, Xin Ci had personally shot and killed his lover, the corporation's leader who controlled half the Federation. The whole world was in an uproar.
He wasn't the organization's attack dog. He was a true star of the Federation.

Xin Ci's mission had succeeded, and it had failed.
When the mission ended, what awaited him was not the truth coming to light and honors being bestowed, but a thorough purge after a struggle for power.
Stripped of his position as a military officer and put in shackles, Xin Ci found that the encryption protocol originally implemented to ensure the mission went smoothly had become a blade aimed at him.
No one could testify whether he had been sent in as an undercover agent from the beginning, or whether he had only turned traitor at the last minute during an internal power struggle and become a tainted witness.
The organization's remaining members, still at large and beyond the reach of the law without evidence, tried to assassinate Xin Ci. The Federation could not provide him with the protection he deserved, and was even carrying out its own purge.
Xin Ci figured he might as well live like a lazy loafer. The next day, he packed up and fled the Federation's Central City for a small city on the frontier.
He became a respectable teacher in the frontier town and lived quietly for several years, until the day a former classmate found him.
"Xin Ci, he's back."
The man Xin Ci had killed with his own hands was not dead.
At the same time, Xin Ci heard a ding: Protagonist Support System 33 has been activated. Host, please complete the main mission in a timely manner.

Delnis's lover was a liar.
It was only when his lover put a bullet through his heart that he learned everything about this well-behaved subordinate, whose whole heart and gaze had been devoted to him, was an act.
Delnis had never loved anyone and would never love anyone. He was accustomed to measuring everything in terms of profit. Only Xin Ci was the exception.
He gave Xin Ci privileges no one else had ever enjoyed, and power within easy reach. With Delnis's support, Xin Ci climbed to the position of military officer.
After giving him so much, all he got in return was a bullet and a betrayal without hesitation.
Xin Ci betrayed him for the sake of ridiculous beliefs and promises.
Delnis had done nothing at all, yet once Xin Ci left the darkness, he was rejected, ostracized, driven out, and put in shackles.
He gave Xin Ci time to regret and reflect, letting him live quietly for two years.
Two years later, Delnis looked down at his pale, frail lover in shackles and said coolly, "Xin Ci, how did you end up such a mess after leaving me?"
He would make Xin Ci understand that only the cage he provided could be Xin Ci's home.
*
After Delnis, that lunatic, found him and locked him up, Xin Ci decided to struggle a little. For example, send him away to prison one more time?
...Or make him love him even more.
Then use Delnis to complete the mission again.
A calculating, sickly top who knows how to say what people want to hear, paired with a powerful bottom with an overwhelming need for control

2. The bottom has an extremely strong need for control and uses cruel methods. He will deprive the top of his senses and mentally control and brainwash him.
3. There are all sorts of people regretting their past actions, including former classmates and colleagues. The top has self-destructive tendencies, is chaotic neutral, doesn't care about his own body, and treats everything like a game.
Theme: Never forget your original aspirations, and keep striving to improve every day.
