The bottom transmigrated into a book, becoming the unlucky master in a classic master-disciple story who was destined to be [beeped] by his disciple after the disciple turned evil.
The bottom: “...”
But he was straight!
He tried to negotiate with the System. “Do I really have to follow this plot? How about I become sworn brothers with the protagonist right now? Is it too late?”
System No. 220 reassured him. “Host, there’s no need to worry. The System has replaced the original story. The protagonist is now a proper, overpowered hero, and you’ll be his master, guiding him.”
Phew, why didn’t you say so sooner?
The bottom relaxed and devoted himself to teaching the protagonist. They explored secret realms together, he helped the protagonist break through and protected him during cultivation, turned away his swarm of admirers, and imparted everything he had learned. At last, he watched with satisfaction as the protagonist became the most powerful person below the Transcendent Realm.
As usual, he walked over and patted the top on the shoulder. “Not bad. Good job.”
The top stared at him. His lips hadn’t moved, yet the bottom heard his voice in his mind.
“...Such a slim waist.”
The bottom: “?”
Was he imagining things?
But the top stepped forward first, wrapped an arm around the bottom’s slender, pale waist, and looked steadily into his eyes. “Is that all? Aren’t you going to reward me, Master?”
The bottom: “???”
At the same time, a cold, mechanical voice, completely different from his own System, rang in his mind.
“System No. 287 is obliged to remind you that your target is scheming and has yet to reveal that he has a System. Host, do not let your guard down.”
“It’s all right,” the top’s amused voice sounded again. “Look, he’s so scared he can’t move.”
The bottom: “???”
1. Scheming, reserved top x sharp-tongued, innocent bottom.
2. Or perhaps you could sum them up as fake straight guy, real overpowered hero x fake overpowered hero, real straight guy (.)
3. My version of cultivation. No serious plot, most likely a two-person romance.
