After I Used and Abandoned the Beautiful Immortal Venerable

[A sharp-tongued, beautiful and tragic, unhinged, devoted attack x a sunny, universally adored receiving character]

In my first life, I was his master, and he was my disciple. The System told me to win over the Child of Destiny, and that it would take me home once I succeeded.

So I brought the boy back to the sect, healed his wounds, taught him cultivation, protected him, and made sure I was the only one in his eyes.

After I got the success notification, I followed the plan and died alongside the Demon Lord at the time. The color drained from his face. Like a madman, he fought his way alone into the middle of the demon army, then hesitantly touched my cheek, his eyes filled with panic at the thought of losing me.

The mission was complete, and I was ready to go home.

But the System said our fates were still entwined, so I had to be reborn to settle things between us;

In our second life, our roles were reversed, and I became a new disciple who had just joined the sect.

The System said that this time I only needed to fill the hatred meter to return home.

So I obediently tricked him into jumping into the Abyss of Demonfall, took someone else's hand in front of him, and trampled his sincere love into the dirt until it was ground to dust, leaving him utterly disillusioned with me.

I succeeded again, just as I expected, and died by his sword.

He still held me in his arms, his gaze numb and cold, swearing to hunt me down for all eternity.

The hatred meter was full, but the System said he hated me too much, so I had to return and clear up the misunderstanding and resolve the hatred;

And then came the third life.

I had only just been reborn as a low-level grass demon when he captured me before I could even put my plan into action...

He gripped me by the throat and asked, "Was it fun messing with me? Isn't it my turn now?"
