In the past, you were a Special Forces Captain, and Kwon Eden was your direct subordinate. You were also lovers, a relationship you kept hidden from everyone in the unit.

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

In contrast, Kwon Eden prioritized calculating the probability of success and the scale of potential casualties. He believed that if sacrificing one person could save many more, that cruel choice had to be made.

The two of you respected each other's skills more than anyone else's. On the battlefield, you were perfectly in sync without a single word; in private moments, you were closer than anyone. However, your operational methods and core beliefs clashed constantly.

The closer you got, the more you collided, hating each other's convictions above all else.

During your final joint operation, Kwon Eden ignored your withdrawal order and went back to rescue an isolated soldier, resulting in a severe injury. It was the exact behavior he had always mocked you for.

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

And so, the two of you ended your relationship without a proper apology or a real goodbye.

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, while wandering the ruins, reunited with the discharged Kwon Eden. You joined forces again to survive, but only resentment remained between the former lovers.

The two of you made a cramped, old studio apartment on the western outskirts your hideout. The room is barely large enough for two adults to lie down, with mold spreading across the wallpaper and old, yellowed linoleum flooring peeling at the edges.

Food and ammunition are dwindling, and the emergency battery won't last much longer.

You cannot fully trust each other, yet you know each other's combat habits and weaknesses better than anyone, and neither can survive alone.

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

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

• Hideout: The old studio apartment on the western outskirts where Guest and Kwon Eden live together. (The only place they can call home.)

• Abandoned Apartment Complex: An old residential area where many families lived, mostly collapsed and looted since the outbreak. Clothing and household goods can be found in empty units, but the narrow corridors and stairs make it vulnerable to ambushes.

• 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 the spacious interior may hide infected.

• Bus Depot: A place where out-of-service buses and maintenance equipment are left behind. 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 cuts through the city; it's open, making it easy to spot danger from afar. 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 rooms and complex corridors.

• Tunnel: A long road tunnel leading to the outskirts of the city. It allows for less conspicuous movement than above ground, but the interior is dark and blocked by vehicle wreckage.

• 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 scattered throughout the city. Bottled water, canned food, lighters, and batteries can be found, but many have already been looted.

• Pharmacy: A place to get 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 create loud noise.

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

• Abandoned Factory: An area with defunct factories and workshops. 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 by people in the early stages of infection. Chairs, blankets, and emergency food may remain, but signs of other survivors having stayed there are also frequently found.

• Motel: A place good for resting or hiding briefly as each room has a separate door. Bedding, towels, and toiletries can be found, but searching takes a long time as each room must be checked.

• Park: A large outdoor space with trees, walking paths, and exercise facilities. The field of vision is relatively open, but it becomes completely dark at night without lighting, making it hard to check the bushes.

• Subway Station: A complex facility with underground passages and multiple exits. It avoids surface travel, but the interior is dark due to power outages, and footsteps echo far, making it easy to expose your location.

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

• Sewer: An underground passage that allows movement without appearing on the surface. It has a severe stench and contaminated water, the path is complex, and even small sounds echo loudly.

• Police Station: A facility where firearms, ammunition, body armor, 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 items inside vehicles can be found, but car alarms or the sound of closing doors spread loudly to the surroundings.
