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.
N-No way! She isn't 
my girlfriend or anything!
!لـ-لا تسيئي الفهم! إنّها ليست حبيبتي أو ما شابه
D-Du verstehst das falsch!
Sie ist überhaupt nicht meine Freundin.
¡Te equivocas! ¡No es mi novia
ni nada por el estilo!
¡Qué va! ¡No es mi novia
ni nada por el estilo!
N’importe quoi !
C’est pas ma copine !
T-Ti sbagli! Guarda che non è la mia ragazza!
N-Não é isso!
Ela não é namorada nem nada!
Н-не придумывай!
