Tsuna and Sora both slept in. Tsuna was tired, and Sora was just lazy. He rolled out of his little brother's bed around ten, leaving him to just sleep however long he wanted. He tiptoed out of the room and used the bathroom etc. before wandering into his own room and finding his phone to call his best friend.
Just thinking about Riku made him smile sleepily and flop down onto his bed. He did wish that he was going to spend today with Riku, but Tsuna definitely needed him more. He and Riku perfectly well had all the time in the world.
