Tsuna shrugged. He wasn't sure. "Maybe Sora tried to bring it up and Riku didn't care?" Tsuna suggested. He could imagine that something like that would frustrate Sora. He also maybe wondered if Sora not only realized they were dating, he was happy that they were dating, and wanted Riku to want it, too, but Riku didn't. He didn't say that to Gokudera, though.
"Maybe," Sora replied, unenthusiastically. He was lying on Riku's bed, face buried in Riku's pillow. It was like he WANTED to...but it wasn't like it BOTHERED him that...he didn't know anymore.
