Christian was not able to give an answer to his sister immediately when she asked him to rest, even though she made an adorable pitiable expression with her face, hiding under it her worry.
He took a moment to reflect on the problem, knowing full well that he couldn't keep pushing himself like this, as he will arrive at his limit sooner or later, and after some thought, an idea finally struck him, and he said.
"How about we sleep in the same room then?"
Christian, after asking her opinion about the only idea that came to him, one where he could respond instantly in case of an emergency, proceeded to explain the reasoning behind it. And after he finished, his sister, seemingly not needing any time to think, immediately replied.
"You really didn't need to explain that much; that was a nice idea, after all."
