Kaito was a bit concerned that Kiibo was so reluctant to take care of himself, but he would get him to do so at some point. Eventually he wouldn't have to worry about him since he would be taking care of himself on his own, but at the time, he would have to make sure that he did anything. He didn't really mind, though, as he was completely focused on helping his friend.
"Thank you," he responded softly. "It may be difficult at first, but I'm here, and I'll help you."
