Rin finds out that Hayato and Ui are living together! Infuriated and shocked, she has to snoop around for evidence of foul play...and get in their way as much as possible.
But just remember this...
Aber dir muss eine Sache klar sein …
Pero al menos recuerda que…
las chicas no son solo partes…
Ma ricorda una cosa...
Mas quero que você se lembre de uma coisa: 
garotas são mais do que essas "partes".
