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 didn't have anything to do with conquest.
En realidad, no hice nada para conquistarla.
Pero en realidad no hice 
nada para conquistarla.
Não tinha nada a ver com a conquista.
