Naruto: One Last Smile

Naruto is willing to do for others above himself. This means that he's willing to step aside so the one he loves can find happiness. How can he explain this to the people he considers his second parents? (This is Narusaku implied. Sasusaku is present. This is a one shot) (Please don't bash this fic, it took a lot of heart to write. Please only leave positive feedback, thank you.)
