When Nagomi hears that Chizuru's birthday has already passed, she decides to throw a combined party for both her and Kazuya, and she refuses to take no for an answer!
Come on, Kazuya. 
It's not like we live in a mansion.
مهلاً يا كازويا، ليس كأنّنا نعيش في قصر
Was redest du denn da, Kazuya?
Wir haben nur eine kleine Wohnung.
Ne dis pas de bêtises.
Ma che dici, Kazuya?
Non è mica una reggia!
Pra que isso, Kazuya?
Nossa casa não é grande coisa.
