"No movement restrictions..." Dabi shook his head, looking César over before continuing. "Considering the time frame, maybe it's better if it's something simple?"

It sounds so much like a 'duh' moment but then, Dabi's voice always is sort of flat like that. Also no, he probably wouldn't feel that comfortable letting someone he barely knows, who is also one of his friends boyfriend, that close to him. Sorry César, you're a good man but Dabi doesn't often trust 'good men'.
