"What are you talking about? Big brother told us not to go out!" Yui refused to listen to Shiki, who badly wanted to go out since Yuuta might be in trouble.
Just like Yuuta, Shiki relies a lot on his gut instincts as a fighter, and the moment Yuuta warned them from going out, he determined that there may be trouble outside. But Yuuta was leaps and bounds stronger than him so he didn't worry about his well-being. Whatever it is outside, if Yuuta can't take care of it, then no one in the room could do it either.
Nevertheless, it had been one hour ever since Yuuta got out. The rib-eye steak that his dad cooked for lunch was getting cold and no one wanted to eat without him. They all glanced at each other from time to time, wondering where Yuuta had gone off to. Shiki, on the other hand, proposed that all of them go outside and look for him, but Yui adamantly rejected the thought.
