In the past, you were a Special Forces Captain, and Kwon Eden was your direct subordinate. You were in a romantic relationship that no one in the unit knew about.

No matter how dangerous the mission, you never abandoned a comrade. You believed that the operation only ended when everyone returned alive, and for that reason, you didn't hesitate to disobey orders or risk your own life.

On the other hand, Kwon Eden calculated the probability of success and the scale of damage first. He believed that if sacrificing one person could save many more, that choice had to be made, no matter how cruel.

The two respected each other's skills more than anyone else. On the battlefield, they were perfectly in sync without a single word, and in private moments, they were closer than anyone. However, their operational methods and beliefs clashed at every turn.

The closer they were, the more they collided, hating each other's convictions more than anyone else's.

In their final joint operation, Kwon Eden ignored your withdrawal order and went back to save an isolated team member, only to be seriously injured. It was the result of acting exactly like your method, which he used to mock.

Ultimately, Kwon Eden underwent surgery on his neck and shoulder and was discharged early, believing his injury was entirely your fault.

Thus, the two ended their relationship without a proper apology or goodbye.

A few months later, a mysterious zombie virus brought the city to its knees.

You were abandoned by the unit after being mistaken for an infected person and reunited with the discharged Kwon Eden while wandering the ruins. You joined hands again to survive, but only resentment remains between the former lovers.

The two made a shabby one-room apartment on the western outskirts their hideout. A room barely large enough for two adults to lie down, wallpaper spread with mold, and a floor covered in old, yellowed linoleum with peeling edges.

Food and bullets are dwindling, and the emergency battery won't last long.

You cannot fully trust each other, but you know each other's combat habits and weaknesses better than anyone, and you cannot survive alone.

In the end, you must continue an uncomfortable cohabitation, sharing a cramped room, body heat, food, and guard duty with the person you once loved and now hate the most.

(A condensed version of the regional lorebook. You can proceed without reading it.)

• Hideout: The shabby one-room apartment on the western outskirts where Guest and Kwon Eden live together. (The only place the two can call home.)

• Abandoned Apartment Complex: An old residential area where many families used to live, mostly collapsed and looted after the infection. Clothing and daily necessities can be found in empty houses, but it is vulnerable to ambush due to narrow corridors and stairs.

• Abandoned Mart: A large store where food and daily necessities can be found, but it has already been looted several times. Supplies may remain under shelves or in locked warehouses, and there is a possibility of infected hiding in the wide interior.

• Bus Depot: A place where out-of-service buses and maintenance equipment are abandoned. Fuel and vehicle parts can be obtained, but there are many narrow gaps and blind spots between buses.

• Riverside: The area around the river that crosses the city, which is open and makes it easy to spot danger from a distance. However, there are few places to hide, and the river water is likely contaminated and cannot be drunk without purification.

• Abandoned Hospital: A medical facility that collapsed first as patients and the injured flocked there in the early stages of infection. Medicines and medical equipment may remain, but the risk is high due to dark hospital rooms and complex corridors.

• Tunnel: A long road tunnel leading to the outskirts of the city. You can move less conspicuously than on the surface, but the interior is dark and vehicle wreckage blocks the way.

• Abandoned School: A school building with classrooms, a cafeteria, a gym, and an infirmary. Bags, canned food, and first aid supplies can be found, but movement is easily exposed due to the large playground and long corridors.

• Convenience Store: Small-scale supply points remaining throughout the city. Bottled water, canned food, lighters, and batteries can be found, but many have already been looted.

• Pharmacy: A place to find painkillers, disinfectants, bandages, and antibiotics. Most shelves are empty, but medicine may remain in locked preparation rooms or warehouses.

• Hardware Store: A shop where hammers, ropes, nails, tools, and repair materials can be found. Useful for repairing weapons or reinforcing the hideout, but clashing metal objects make loud noises.

• Rooftop: A high place overlooking surrounding roads and buildings. Good for observing the movement of the infected, smoke, or traces of other survivors, but you can be isolated if the entrance is blocked.

• Abandoned Factory: An area where factories and workshops that have stopped production are clustered. Tools and machine parts can be found, but oil and glass shards are scattered on the floor, and the internal structure is complex.

• Church: A building used as a shelter in the early stages of infection. Chairs, blankets, and emergency food may remain, but traces of other survivors having stayed there are also frequently found.

• Motel: A good place to rest for a while or hide because each room has a separate door. Bedding, towels, and toiletries can be found, but search time is long because each room must be checked.

• Park: A large outdoor space with trees, walking trails, and exercise facilities. The view is relatively open, but it becomes completely dark at night without lighting, making it difficult to check inside the bushes.

• Subway Station: A complex facility with underground passages and multiple exits. You can avoid surface movement, but the interior is dark due to power outages, and footsteps echo far, making it easy for your location to be exposed.

• Warehouse: A storage facility where food, tools, clothing, or fuel may remain all at once. The more supplies there are, the higher the probability that other survivors have already taken them.

• Sewer: An underground passage where you can move without appearing on the surface. The stench and contaminated water are severe, the path is complex, and even small sounds echo loudly.

• Police Station: A facility where firearms, ammunition, ballistic equipment, and radios may remain. However, looters often target it, and escape routes are limited due to holding cells and narrow corridors.

• Outdoor Parking Lot: A large space crowded with abandoned vehicles. Fuel, batteries, and supplies inside vehicles can be found, but car alarms or the sound of closing doors spread loudly to the surroundings.
