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.
Sorry. I sent her home 
without clearing anything up.
آسف، صرفتُها إلى المنزل دون توضيح أيّ شيء
Entschuldige, dass ich sie nach Hause schickte,
ohne das Missverständnis zu klären …
La envié a casa
sin aclarar las cosas, lo siento.
La he mandado a casa
sin aclarar las cosas, lo siento.
Désolé. Elle est partie
sans rien vouloir entendre.
Ti chiedo scusa. È tornata a casa
 senza che sia riuscito a chiarire tutto.
Desculpa. Mandei ela para casa
sem esclarecer nada.
Прости, что так ничего ей и не объяснил.
