Jinwoo is taking on the solo dungeon/raid/mission thing and learning he's gotten much stronger than he expected. He's also getting crash course on buying items, looting those he's beaten, and how to level up. But there's a big boss waiting below and he needs to level up more before he takes on that challenge. Even after leveling up multiple times over, he's still not sure he's strong enough but faces the boss anyway and takes it down in a way that surprised the heck out of us. After that, a monster is loose on the streets and Jinwoo helps from the shadows, easily taking it down and walking away without any credit taken.
