Being a Background Character Isn't Hard, but My Life Is

Chu Jin was an utterly ordinary passerby, a character with no outstanding abilities or talent, destined to be the most unremarkable person in the protagonist's growth story.

At last, Chu Jin realized that he was just a passerby in countless worlds. No matter how he pursued the male lead, he was only making a fool of himself.

He was reborn every time he died, and there was no escaping the fate of a passerby who would eventually disappear into the crowd. He might as well lie flat.

But who could have guessed that after he gave up and lay flat, he would become the protagonist's white moonlight?

The Cultivation World:

A powerful cultivator bottom x a mortal doctor top

The protagonist top, who had spent his entire life pursuing immortality through cultivation, suddenly realized that Chu Jin, who had always followed close behind him, had changed.

Chu Jin no longer kept his gaze on him. Instead, he used his medical skills to treat countless commoners. He was like a radiant, warm sun, and he no longer said, "Even without a spiritual root, I want to cultivate alongside you."

The protagonist top began to fall apart. He clutched Chu Jin's wrist tightly. "A-Jin, come to the Cultivation World with me, okay? I'll find a way for you to cultivate!"

Chu Jin, whose features were beginning to age, shook his head. "No need. Cultivation isn't all that great."

After all, having lived countless lives, he'd long since stopped caring about immortality.

Gradually, a rumor spread through the Cultivation World: a great cultivator was doing everything he could to keep a mortal by his side, even defying the heavenly cycle of reincarnation to forcefully extend the mortal's life.
