His Dark Desire: Tales of a Yandere - Chapter 15

This story is centered around the man named Yi Ji-Hyuk, who has spent 1000 years in a Medieval Western fantasy-like world before returning back to the modern-day Earth. When he returns, he finds that his home is facing monster threats, and that humans with superpowers have appeared to protect the innocent people of Earth.

The Heavenly Dao exists.

It decides what is right and what is wrong. To act against it is to sin, to act according to it is to be blessed by its graces.

The world of cultivation is difficult, an unchanging principle. Yet there are those who are cherished by the Heavens, cuddled into rising above all and everyone else. How can this be? Why must this be?

What is moral and just? What is evil and immoral?!

WHY DOES IT GET TO DECIDE?!

So we, the Sinners, we act against the Heavenly Daos, grasp our own fates in hopes of truly overturning them.

This is a Journey of a young boy born Blessed, but turned Sinner.

The greatest sinner of them all.

Protagonist travels between different anime worlds to right wrongs and uncover his reason for being along the way.

Shao Qing’s only regret in life is that she blindly fell in love with a worthless man. She gave up everything for him, but in exchange was run over by his conniving mistress when she was close to her delivery date. Fortunately, Heaven left her a way. Crimson rain fell from the sky, the end of the world arrived, she resurrected in the morgue and gave birth to a little monster. Turning into a half human, half zombie freak; her son neither human, nor monster; they have no other choice but to rely on zombies’ crystal nuclei to develop their special abilities and continue living. This debt, she’ll definitely repay that cheating couple!
