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.
Just don't blame me if something 
happens to your place, okay?
لا تلُمني إذا حدثَ شيءٌ لمنزلك فحسب، اتّفقنا؟
Aber ich bin nicht schuld, wenn du
deine Wohnung nicht wiedererkennst.
Pero no me culpes
si pasa algo en tu casa, ¿eh?
Pero no me culpes
si pasa algo en tu casa, ¿eh?
S’il arrive un truc,
tant pis pour toi !
Ma se dovesse accadere qualcosa,
 non prendertela con me, ok?
Não reclame se acontecer
algo na sua casa.
Если с квартирой что-то случится,
пеняй на себя!
