Amane's mother, Shihoko, arrives at the apartment without warning while Mahiru is visiting. Amane asks Mahiru to hide, but Shihoko eventually finds her, and the two neighbors frantically try to correct Shihoko's assumption that they are dating. Nonetheless, Mahiru is touched by Shihoko's motherly kindness. After Amane sees how happy Mahiru is to be called by her first name, he tries calling her "Mahiru" too. From that day on, the neighbors call each other by their first names.
My parents would never call me 
by my name. Ever.
مُحال أن يناديني والدايّ باسمي. أبداً
Meine Eltern würden mich nicht
mit Namen ansprechen. Niemals.
Mes parents ne feraient jamais ça.
Loro non mi chiamerebbero mai così,
questo è certo.
Meus pais nunca me chamariam
pelo meu nome. Nunca.
Родители меня так не зовут.
