At least their grins match each other for how big and delighted they are, and he doesn't, for a moment, find any of what Ned's saying embarrassing. Quite the contrary, really. He's surprised he'd had the courage to kiss Ned out here in the first place, and he's even more surprised that Ned had returned the kiss, but what he's not surprised by is how happy it makes him.

"I really like you, too. I guess that was probably obvious. I wish I could kiss you again. Really kiss you, I mean. In front of other people."

And now he's just going to hide any of his own embarrassment by taking a long sip of his hot chocolate. He's always known that he has a tendency to get attached to people quickly, but the intensity of the attachment he feels to Ned is something he's never experienced before. It has him confused, certainly, but pleased, too.
