It's the night before the Mai High Festival.  Keima and Chihiro are alone on the roof of the school.  Chihiro seems confused by Keima's behavior, but he continues with his conquest.  But as Keima makes his move, Chihiro says something unexpected.
Man, I wasted all that time on an empty route.
Rayos, perdí mucho tiempo 
en una ruta inútil.
He perdido mucho tiempo en una ruta inútil.
Cara, eu perdi todo aquele 
tempo em uma rota inútil.
