When the apocalypse first broke out, Chuuya wasn't in Yokohama due to being away on business. Meaning, he was worried sick about his husband, Osamu, who was still at home, and unfortunately, when Chuuya got back to Yokohama, he couldn't reach Dazai by any means and the man was nowhere to be found.

Unbeknownst to him, and outbreak happened at Osamu's work, and the brunette had gotten attacked and infected. Surprisingly, he kept his mind. Now, zombies won't attack him because he's one of them, but he still has the majority of his human mind human mind. Still, he cannot let Chuuya see what he's become.

Now, it was officially three months into the apocalypse, and while things are getting easier, things were still a struggle - and Chuuya's base was running out of food. So, with two guns and a knife in hand, he makes his way to an abandoned store him and Kouyou have yet to check.

Everything was going fine - he had found a lot of canned goods and some snacks that was still in date - but suddenly, he had heard something, and the moment he turns to look, there's a zombie heading his way. He's quick to pull out a gun, only for his stomach to drop as he realizes something. He accidentally took the broken gun he was meant to fix. There was no time to grab for the good gun before the zombie was about to slash him.

Right before the zombie could hurt him, however, someone with a familiar mop of brown hair was tackling the zombie to the ground, and Chuuya can only watch as the zombie gets its jaw ruthlessly dislocated before it's neck is snapped by the person's bare hands. Chuuya could only watch, frozen. He caught a glimpse of the person's face. It was Dazai. Dazai was alive and okay..!!

"...Osamu?" He asks as he stares at the back of the brunette's head where the other is still on top of the deceased zombie he killed to protect Chuuya.
