It's really not something Cloud thinks about much, but he's pretty much come to terms with the fact that other people love him. A lot of other people. He doesn't understand, but that doesn't stop it from being true.

He hugs her a little tighter, a tiny smile forming on his face again. "Yeah. I do." If Cloud really does have a soul then maybe he's actually worthy of love after all, because that would mean he is capable of loving someone else in return.

Then again, with how upset Shoshosu seems to be, she might have just found out he didn't have a soul after all. That would explain a lot, like the Lifestream spitting him back out every time he ended up dunked in it or dissolving into it. All poison, no life.
