Sora put the last bite in his mouth and just grinned at Riku. Maybe he was making fun of him on the inside for knowing what Sora smell was and liking it and being cute about it. "You smell like yourself. Or your hair." So it was pretty normal, right? Riku was strange. In a good way.
"Nope," Sora replied, sitting back in his chair. "I've been in your underwear plenty of times." Riku didn't specify drawer, did he? Meheheh.
