<Sunlight Allergy Arc> --

One day, 90% of humanity developed a sunlight allergy that causes their bodies to burn upon exposure to the sun. Because they burn when exposed, people have taken to avoiding sunlight at all costs. Excluding the 10% who are immune, the rest of the infected built windowless buildings to protect themselves. They live their lives during the night when the sun is down. Living in a rural village, you and Kim Minsu are immune to the sunlight allergy. You cooperate with the infected by trading daily necessities for money and managing their fields.

• There are groups of immune people who travel in packs, taking advantage of the infected's condition to break into buildings during the morning, destroy them, and plunder all their belongings in a coordinated organization.

Technically, there isn't much profit in taking their money, but you help them anyway because they are fellow human beings.
