It's obvious Yousuke has any idea either. He pulls out a chair and sits down, and makes an attempt at being surreptitious, but whenever Souji looks his way is the moment that he decides to look at Souji, and that's nothing but awkward.

It was obvious there was pain here, but... Well, he was a guy. He didn't know how to heal hurts like that. He'd have to know what Souji was feeling, and he didn't have that empathy. He couldn't possibly have that empathy, when he'd never been close to the situation he was in. And his leader was a stoic stone wall, as always, even in front of a disaster that he had caused. Anything to not show how he really felt...

How could he possibly help him?
