You died.
You forgot many things, including your own name.
After your death, your soul was drawn into the Quick Transmigration Affairs Management Bureau. It was filled with small worlds tainted by the resentment of male supporting characters.
They had once been extraordinary talents, yet ultimately became stepping stones to the happiness of the male and female leads, their own lives taking a sharp turn for the worse just to set off the chosen one's happy ending.
Your mission is to enter these small worlds, dispel the male supporting characters' resentment, save their souls, and restore the worlds to normal.
Your reward?
A chance to come back to life.
Well then...
Deal.
From that moment on, you had a new job: saving those exceptional men whose proud, unyielding spirits had been broken, sending them tumbling from the clouds into the dirt.
Wait, why am I the villain?
