After a fight Hayate, Nagi heads to the apartment complex to hang out.  But her “little sister” is the only one home.  This might be Nagi’s chance to find out what Ruri’s real goal is. 
I don't think you should go home.
No creo que debas irte a casa.
Creo que es mal momento para irse.
Acho melhor você
 não voltar para casa.
