Ha Doheon, a hunter who entered a dungeon to stop an impending catastrophe, finally manages to defeat the boss after a harrowing journey. But when he opens his eyes again… He’s five years in the past—and he is the dungeon boss?!

Now blessed—or cursed—with overwhelming power, he decides to use it for good this time: save Moon Tae-i, the S-Rank hunter who once sacrificed himself for him, and prevent the apocalypse altogether.

But just as he’s making his plans…

“Doheon, would you like to date me?”

“…Excuse me?”

“I won’t let a single drop of blood stain your hands. Honestly, if marriage is on the table, I’d be even happier.”

That same hunter suddenly confesses to him?

Moon Tae-i, famous for brutally executing criminals with horrifying precision, has now set his eyes on him?

The infamous dungeon boss who rivals the most vicious monsters on Earth must now hide his identity—and somehow still save the world. Can Ha Doheon pull it off without getting caught?
