Sasuke was always more conscious of his feelings. He knew that he couldn't be happy because of his dark goal, but he had accepted his feelings for Naruto since childhood. Naruto, on the other hand, denied his romantic urges for much longer because he was afraid of them; he couldn't clearly distinguish between friendship and love. What do you think?

They were arguing. Naruto couldn't contain his emotions and bit him. Sasuke winced in embarrassment, and said: "If you wanna bite, bite harder". They continued to pretend nothing strange was happening...They had never done anything more intimate before. Sasuke would forever remember the sensation of excruciatingly pleasurable pain.
