After 20 years of dedicating his life to opera ever since he had quit the performing arts high school, he had failed at an interview. Losing his motivations, Jo Yunjae depended on alcohol to live out his days until one day, he had been sent back 20 years in time, to the day before his high school admission.

A fluffy, sweet modern GL story about a mature older women and a cute university student.

Born without a mana circle into one of the most powerful family of hunters in the country, Luthra was the ultimate failure. Deemed trash and disowned, he was cast out with nothing but the clothes on his back and a cold, self-hating resolve.For five years, he trained his body to its breaking point, only to discover his weakness was a lie. His power wasn't absent—it was a paradox. A 'Negative' mana circle so volatile it had to be sealed by a god at his birth, lest it annihilate his very soul.Now, the seal is cracking. To prevent catastrophe and seize his own destiny, Luthra is given a key: The Negative Leveling System. In this world, power means leveling up. For Luthra, true strength is found by leveling down.Armed with a simple industrial chain and an unshakable pragmatism, he begins his hunt. Every monster core he absorbs pushes him deeper into negative levels, unlocking twisted skills and an incomprehensible strength the world has never seen.They called him a zero. But in a system where Level -10 is stronger than Level 1, Luthra is about to show them what true power looks like from the bottom.

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.

This in turn created a new species known as the mixed-blood.
