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.
it's natural that I'd fall in love, 
even with a lowlife like him!
no es mi culpa que me enamore de esa basura!
no es mi culpa que me haya 
enamorado de esa basura!
é normal que eu me apaixone, mesmo que seja
 pelo maior cafajeste do mundo como ele!
