Ryuutaro removed himself a bit from Hayato, smiling slightly.
"That's not necessary, but thank you a lot...", he reached up and let his fingers brush through Hayato's hair softly, "You go and do your report and then just go to sleep."

Ryuutaro didn't exactly know what he wanted to do, but somehow relaxing wasn't one of the options. He felt so far behind and that just needed to change. He couldn't have Hayato (and possible someone else, which would be worse) rescue him all the time.
