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 if you're asking me about Christmas 
plans, does that mean you have some?
،لكن إذا سألتني عن مُخطّطاتي للكريسماس
فهل هذا يعني أنّ لديك مُخطّطات؟
Hättest du denn einen Vorschlag, weil du nach
meinen Weihnachtsplänen fragst, Amane-kun?
¿Me preguntas sobre la Navidad
porque tienes planes?
¿Me preguntas sobre la Navidad
porque has hecho planes?
Si tu me demandes si je suis libre,
c’est parce que tu as prévu un truc ?
Però, come mai me lo chiedi?
 Tu hai qualche impegno per Natale?
Se me perguntou dos planos para o Natal,
imagino que você tenha os seus?
Раз ты спросил о моих планах, 
Аманэ, у тебя самого они есть?
