Synopsis: Only people with superhuman consitutions, known as hunters, can fight against monster dungeons. Siblings of hunters are exempted from army conscription, so some families adopt orphans who demonstrate the potential to become hunters in adulthood. Yeon-woo (MC) is one such orphan, becoming the big brother to Mo Jeong-woo (ML). Yeon-woo is determined to become a hunter to protect Jeong-woo, but Jeong-woo becomes prickly whenever the topic comes up. Five years later, Yeon-woo is deployed to what may be his last stand.
Review: The world-building is the best part about this manhwa. The way different facets of society treat hunters is very compelling. I also especially liked how the time mechanics of the dungeon closes the age gap between MC and ML. However, at the end, any care is thrown out in favour for smut—in a dungeon in which MC's entire squadron have died. The story stops there, which is a bit disappointing, but readers say that the original author passed away before they could finish writing, so I understand.
