Blood Lord

Fourteen years after his brother vanished in a dungeon, potion broker Cheon Si-young gets a chance to find him when S-rank hunter Ji Hae-geon offers to reopen it—if Si-young joins his guild.

After becoming trapped in an S-rank linked dungeon, Si-young uses his hidden power to save everyone and erase their memories, including Hae-geon’s.

But Hae-geon remembers the kiss that triggered Si-young’s ability—and proposes a contract relationship.
