Jinwoo joins a party led by Hwang Dongsuk to meet the headcount necessary for a C-Rank dungeon. Joined by another temporary hire, Yoo Jinho, the party defeats beasts without much trouble, but Jinwoo has suspicions about the group's lack of a healer.

As Jinwoo continues his training, he completes a daily quest one day by doing more than the quest requires, and a key that leads to a certain item appears in front of him.
