Kinsei seemed to consider the idea of a sleepover for a moment before shrugging his shoulders. He was sure with such a lovely house there would be plenty of room, and he wouldn't be a burden, but it was surprise enough that they had gone to her home in the first place. She had been an excellent host, even allowing him to borrow one of her trainer's clothes for what ended up being a sparring match. "That does sound fun, but would it be appropriate for you to have a boy you just met today stay in your home overnight? An older one, no less." He chuckled slightly at this, showing that at least part of him was joking. It was still a good point, though.
