Sora shook his head. "Tsuna is a good kid, and stubborn." So he'd be annoyingly good always, even if Gokudera was trying to get him to not be. "Hopefully, he'll teach Gokudera a thing or two." That would probably be the better solution.
"Tsuna needs some friends, and it wouldn't hurt to have a few that could keep him from getting bullied," Sora said. He'd like Tsuna to have friends before he had to leave him. He was pretty safe right now with a big brother that's a senior, but you never knew what would happen in the future.
