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.
I'm doing it all because I want to.
Ich mache das alles, weil ich es möchte.
Todo lo hice por gusto.
Siempre hago las 
cosas porque quiero.
Je n’ai fait 
que ce qui me plaisait.
Faço tudo porque gosto.
