Among the FansEdit

SasuSai isn't a popular pairing. The relationship between Sasuke and Sai is considered a crack pairing. There is not much evidence of their relationship was shown in the manga or anime. This pairing was supported due to Konohamaru's Sexy: Boy on Boy Technique. Konohamaru transform into naked Sasuke and naked Sai staring at each other closely is like they are so close that they are about to kiss each other. The other reason this pairing was supported is due to what Sakura said to Naruto about Sai that Sai looks alike Sasuke.
