At last Haruki realives Kazuma's true feelings, but while he's confused at this sudden turn of events he can't hide his joy that the girl he loved best likes him too.
And the next thing I know, 
I've lost everything.
Und danach ... habe ich alles verloren.
Y para cuando me doy cuenta, lo pierdo todo.
Y cuando quiero darme 
cuenta, lo he perdido todo.
Quand j’ouvre enfin les yeux,
 j’ai déjà tout perdu.
E quando percebo, eu já perdi tudo.
