[I was reincarnated as an F-class Hunter.

…it’s a problem because they don’t treat me that way.]

An unnamed 34-year-old Japanese NEET is evicted from his home following his parents' death.

Upon some self-introspection, he concludes that his life was ultimately pointless.

Walking down a street he intercepts a speeding truck heading towards a group of teenagers, in an attempt to do something meaningful for once in his life he manages to pull one of them out of harm's way before getting himself in the way of the truck and dying.

Awakening in a baby's body, he realizes he has been reincarnated in a world of sword and sorcery.

He resolves to become successful in his new life, discarding his past identity for his new life as Rudeus Greyrat.

“21 days. 7 hundred million won. 29 strangers. One unforgettable man.” Yoon Ji-won never planned to become a substitute driver. He never planned to be locked inside a building for 21 days with 29 dangerously attractive men. And he definitely didn’t plan to have his world turned upside down by a smooth-talking younger guy who won’t leave him alone. After a mysterious interview, Ji-won is thrown into a secretive, high-stakes project with an offer too tempting to refuse. The rules? Obey. Stay. Survive. But when he meets “Number Three,” everything starts to unravel. Cold stares. Lingering touches. A spark that turns into a fire he can't put out. Is it destiny? Or just another trap? For readers who crave intense power dynamics, isolated tension, and twisted attraction wrapped in a sleek, modern BL thriller.

Civilization is destroyed and records lost. Only Dudian survives in a cryogenic sleep. Three hundred years later, Dudian wakes up and must become Dean to survive. Who can he trust in this world overrun by monsters without and within?
