You say that this is wrong; Why does no one stop us?
You say that we'll be caught; Why has no one found us?
You say that I'll regret this; Did you see that in a vision?
You ask me for a motive; Reason is but an illusion.
Sasuke falls in love with Caroline, but she's already in love with Neji. Caroline sees Sasuke as a friend, but unlike Naruto, Sasuke won't settle with being a friend. Up in about the twenty-fifth chapter of "The Half Moon Personified: The Avenger", Sasuke manages to corner Caroline one night, and that's when this scene takes place.
In the poem's third verse, Sasuke's kind of mocking Caroline's ability to see into the future.
