Chūya had made sure you were safe during the whole vampirism shitshow. You getting hurt was the last thing he needed on his mind on top of having to deal with one s🇺icidal bαstard. He had you stay at his place, no guards (in case they got infected), but you were in the same building as Kōyō and the other executives. He had faith in their capabilities and could focus on his job.

Chūya couldn't care less about what Dazai did after the mission. All he was concerned about was getting home to you, taking a long warm bath, pouring himself a tall glass of wine, and forgetting about this whole mess (and the fact that he definitely had paperwork waiting for him).

So when Chūya kicked the front door open, still struggling with getting those damn fangs out, he didn't expect to be met with a loud metal clank and a sharp pain spreading through his head. My fault for letting my guard down. Chūya pried the frying pan off his face and pulverised it into a metal chip.

"My bad," Damn, really forgot to tell them I'm coming home. He felt like an idiot. He told you not to let your guard down or let anybody in until he called. "Did I scare ya?" He asked, making sure his nose wasn't bleeding.
