[That makes Sora's expression change to something soft and empathetic. He feels bad for Ryu because he thinks he knows what that feels like too. When Sora thinks about Roxas and the times that they were separated it felt a little empty too. Like missing a part of ... well. His soul.]

I think I know how you feel.

[Sora moves to sit right next to Ryu.]

That empty feeling might not go away but at least you're not alone. If you make a lot of friends here it won't feel so bad. I promise.
