[A rough outline, written on February 13, 2026, to be polished later]
Jiang Leran is the top, Pei Jian the bottom.
After the Jiang family goes bankrupt, Pei Jian, Jiang Leran's uncle by marriage, takes him in.
They agree that Jiang Leran will look after Pei Jian for the rest of his life, while Pei Jian will make sure he has everything he needs.
But later, Jiang Leran's personality changes completely. He becomes obsessed with pursuing a poor little star and gradually neglects his uncle.
Then one day, a voice appears in his mind and tells him that the world he lives in is a novel, the little star is the protagonist bottom, and he is a cannon-fodder character destined to die early.
Only then does Jiang Leran remember that his life used to be different.
It turns out the world's will influenced him, turning him from a sunny, cheerful boy into an arrogant, overbearing young master who was doomed to be cannon fodder, and making him fall for the little star without realizing it.
But now he understands that the little star is the protagonist bottom he'll never be able to win, while his uncle is the person who loves him most in this world.
Unfortunately, he did many foolish things and broke his uncle's heart, driving them further and further apart.
So his mission now is to treat his uncle well.
"I really know I was wrong." He shuffled forward on his knees in front of Pei Jian's wheelchair, gazing up at him with shining eyes. "I'll be a good nephew and take care of you from now on."
"Really?" The handsome man crossed his hands over his abdomen and looked down at Jiang Leran, his expression inscrutable.
"Really." Jiang Leran nodded vigorously and raised his hand to swear to Pei Jian. "I don't actually like men. I'm not attracted to men."
"..." Pei Jian's gaze lowered behind his glasses, resting on the young man's face. In the end, he decided to give him one more chance.
After that, Jiang Leran saw the error of his ways and began a life devoted to caring for his uncle: he massaged his uncle's aching legs, drove him to and from work, and when his uncle said he liked men, he...
Went out to find him a man.
Unfortunately, his uncle was picky and didn't like any of the men Jiang Leran found for him.
At the same time, Jiang Leran discovered that his uncle had a secret. One night, as he passed his uncle's bedroom, he accidentally heard muffled moans coming from inside.
When he asked Pei Jian about it, Pei Jian only smiled meaningfully and told him not to worry.
His uncle must have been suffering from leg pain in the middle of the night and quietly enduring it.
With that in mind, the next time Jiang Leran heard the sounds, he threw open Pei Jian's bedroom door. "Uncle, you..."
After seeing what was happening inside, Jiang Leran backed out again. "Uncle, you..."
"Come in." His uncle's low, magnetic voice rang out. "Since you've discovered my secret...come help me."
"It's fine if you don't know how. I'll teach you."
P.S. The top is a little silly, not intellectually disabled, just a bit slower on the uptake than other people.
