I love narusaku but why is April 3rd their day?
April 3rd is NaruSaku Day. It is celebrated annually by NaruSaku fans on sites like Tumblr, DeviantArt, and Facebook.
“The day Naruto fell in love with Sakura-chan” was said the 2010 Shounen Jump Calendar.
Alternatively, it could mean “The day Naruto came to like Sakura”. ‘Suki (好き)’ means love and like in Japanese.
