Post-war Seoul, swarmed by mutant mosquitoes. You were just trying to make it home.
After a long ceasefire, North Korean provocations finally reached the city center, and the war began anew with the resulting casualties.
However, South Korea reached the brink of victory much faster than expected. Just as the evacuated citizens began returning to their homes, hoping they remained intact, the enemy deployed their remaining nuclear weapons and secretly developed chemical weapons.
Seoul's sky turned ash-gray. Dust rose from the ruins of the city, and a thick fog of chemical substances settled over the Han River, turning it into a wasteland.
Though the war was prolonged by the enemy's desperate resistance, South Korea eventually emerged victorious.
But the damage across the country was so catastrophic it was hard to feel lucky. Guest, a soldier, was preparing to return home upon discharge, relieved that the threat was gone and dreaming of happy days ahead.
That was until the 'mosquitoes' swarmed up from the Han River.

■ South Korea: Nationwide · Electricity in each region is powered by solar chargers set up by technicians, batteries salvaged from abandoned cars, and small fuel-powered generators. · Internet and communication networks are completely down. · Even in this state, local power players exist at every major stronghold.

■ South Korea: Metropolitan Area, Seoul · The area most heavily damaged by the war. · The city is a gray ruin, and the headquarters of the mutant mosquito legion is located in the contaminated Han River. · With the Han River polluted, the population is suffering from a severe water shortage. · Surviving soldiers and civilians have set up base camps in large subway stations, using them as primary strongholds for survival.

■ South Korea: Han River · A high-risk zone contaminated by chemical substances. · Giant mosquitoes, appearing to be 3 meters long, fly around the riverbanks and collapsed bridges. · The murky waters of the Han River are filled with wrigglers (mosquito larvae) the size of adult men. · The closer one gets to the Han River, the more the mosquitoes' movements shift from instinctive to tactical and organized. · There are rumors among survivors of sightings of mosquitoes with human-like forms.

■ South Korea: Provinces · While spared from direct strikes and pollution, these areas serve as the final line of defense against the southward-migrating mutant mosquitoes. · Surviving leadership has gathered here to maintain a basic chain of command. · The defense line is under heavy pressure as communication is cut and the mutant mosquitoes become increasingly tactical.
In 20XX, the frequency of ballistic missile provocations from the enemy toward South Korea was increasing at an eerie rate.
At first, everyone thought it would just pass like all the other times, but eventually, the provocation reached Seoul, turning from a threat into a horrific attack.
As the sparks of war finally ignited, the soldiers who were looking forward to discharge found themselves heading to the battlefield instead.
The war was gruesome and intense.
After a bloody struggle, South Korea's overwhelming victory was in sight, and citizens who had fled the capital were preparing to return to Seoul one by one.
But the enemy, driven to the edge, finally crossed a line that should never have been crossed.
They poured their remaining nuclear weapons and secretly stockpiled chemical weapons right into the heart of downtown Seoul.
The sky over Seoul, which had been regaining its blue color, suddenly died, turning into a suffocating ash-gray. The collapsed buildings began spewing gray dust once again without pause.
The Han River, which everyone longed to see, was submerged in a bizarre fog as toxic chemicals seeped into it.
Even in that terrible hell, we endured until the end and sounded the cry of victory.

"It's finally over...!"
Wounded soldiers slump down in transport vehicles, some falling asleep, some laughing, and some crying.
"Let's go back!!" "We're finally going home..." "Damn... I actually lived..."
As they rattled along the broken roads overlooking the Han River, they firmly believed they were returning to their normal daily lives, to their long-missed homes.
