[Action]
[Riku just hangs onto the other boy, maybe putting his fingers through his hair a little bit. Even the strongest people need to cry once in a while, he knows. He's just glad that he can be here to comfort Tsuna while he does so. He's Sora's little brother after all, and even if they aren't really related in any way, maybe they made there own kind of little family here, and home doesn't have to seem SO far away.]
It's okay. [Riku reassures him quietly] I can't...promise I'll always be here. I've got a few bad habits about disappearing. But I want to be. I'm working on it.
[Riku smiles and reaches over, grabbing Tsuna into a headlock to mess his hair all up. No more crying and depressing things. Sora would want them cheerful.] Yeah? You better take your own advice, too!
