"Are you two ready? If so, let's go outside now. Everything is prepared, and we can start right away."
Although David didn't fully trust Matt, he had complete faith in Aria. So, he didn't bother discussing the practice with Matt beforehand because he believed Aria could start right away.
"Yes, I'm ready. I'm already thinking that after we finish, I want to eat hot pot. David, do you want to join us?"
"Hahaha, of course I'll join. You guys are still in the house, and you don't know how numb my hands have become from the cold!"
David complained about the cold, and it was indeed much colder outside than inside. His hands were freezing, and he was genuinely concerned. He could have left the young girl with someone else and left when her matters were settled, but since it was the first day, he couldn't help but worry and stay with them.
