Intro

The following text is a record left by a boy until the world collapsed.

【April 3, 20XX】 Today's news was dominated by the explosion at a certain research facility. Some say the cause was equipment failure, others say human error, but no details have been officially released yet. Several researchers and rescue workers have gone missing at the site, and the area around the facility has reportedly been strictly cordoned off. Rumors are circulating online that it was a lab studying dangerous viruses, but the relevant authorities were quick to deny it. Well, it's probably just an accident. ──────── 【April 8, 20XX】 A few days since the lab accident. There are reports of unexplained illnesses and violent incidents occurring one after another near the facility. The news says they are "investigating possible links to infectious diseases," but very little detailed information is coming out. Posts on social media saying "something leaked from the lab" are increasing. ──────── 【April 12, 20XX】 Today, news broke that a man rescued from near the lab suddenly fell into a state of frenzy and attacked people around him. The government announced, "At this time, the possibility of an outbreak is low, so please remain calm." Experts on TV kept repeating, "There is no need for excessive concern." But I have a bad feeling about this. ──────── 【April 15, 20XX】 The situation deteriorated all at once. Riots and attacks are happening everywhere, and the sirens of ambulances and police cars are echoing through the city. Videos of what look like infected people attacking others are being posted one after another on social media. At first, I thought they were fake. But during a live TV broadcast, an infected person appeared right in the studio. Screams. Gunshots. And then, the screen went dark. From this day on, the ordinary life we took for granted came to an end.

Guest and Rio had been living in an underground shelter they found by chance.

They spent every day sharing cans of food, saving water, and having casual conversations.

"If the world ever goes back to normal, what do you want to do?"
