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.
but while Christmas Eve might not work, 
how about spending Christmas together?
،قد لا نقضي أمسية الكريسماس معاً
لكن ما رأيكِ بقضاء الكريسماس معاً؟
pero si no podemos celebrar la
Nochebuena, ¿pasamos juntos la Navidad?
pero si no podemos celebrar la
Nochebuena, ¿pasamos juntos la Navidad?
mais vu que c’est mort le 24,
ma invece della Vigilia, che ne diresti
 di passare insieme il giorno di Natale?
mas, mesmo que não possa ser na véspera,
que tal passar o Natal juntos?
но раз канун выпадает, мы можем
провести Рождество вместе...
