Part of it's shyness - he knows he's the Stormtrooper, everybody knows that, and it does set him apart no matter how much General Organa likes him. Or maybe it's that the General has singled him out, or that the story about Rey's rescue grew in the telling. Either way, the squad he's assigned to likes him well enough but he's found it tough to make friends outside that.

And it's not even that he's never had buddies before. His grin gets a little sheepish. "We had downtime, but we never really had leave. You know? So I don't know if that's how it works or not."
