When Itsuki and Chitose visit Amane's apartment for a Christmas party only to discover that the angel Mahiru lives next door, they instantly become very curious about the relationship. Chitose, obsessed with cuteness, insists on becoming friends with Mahiru. The day after Christmas, Amane notices that Mahiru has a fever. Despite Mahiru's stubbornness, Amane convinces her to stay and rest in his room. When Mahiru sees Amane so diligently taking care of her as if returning the favor she did for him that one memorable day, it seems to put her at ease.
I'm so sorry for occupying 
your bed, and the cooking...
...أنا آسفة لأنّني أشغل سريرك، والطبخ
Es tut mir so leid, dass ich dein Bett in Beschlag
nehme und du für mich kochen musst …
Perdona por ocuparte la cama
y hacerte cocinar…
Perdona por ocuparte la cama
y hacerte cocinar…
Désolée d’occuper ton lit
et de te faire faire à manger…
Mi dispiace di aver occupato il tuo letto, 
non posso neanche cucin...
Sinto muito por ocupar
sua cama, e tem a comida...
Прости, что заняла твою кровать. 
И с готовкой...
