"I did talk to him. He insisted that they're just best friends, and that's the way they act." Riku was such a dumb dumb.
Riku eventually came back into his room and began changing for bed. "Sometimes," he informed Sora, "I think Gokudera must be some sort of divine punishment for being a brat to my sister when we were little."
