"Not bad, boya."
"Huh?"
"Even when aware of the immense difference between you and me…" She walked past him, forcing him to turn around to face her back. "…you fight back. You talk back…even if it's for a silly reason such as 'protecting your friends'."
Naruto noticed Setsuna had inclined her head up, to look at something she could only see in the distant sky.
"A tough man who fights to stand by himself, to not let the world step on him or what he believes in, a man who takes a beating and is willing to get back up…a man who knows what he wants…whether it is an evil man or a goody-goody two-shoes like you…"
Naruto grimaced.
Setsuna turned around to look at him. Naruto found her smile stunning…and disturbing.
"A man like that…is a man I can grow to like."
