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.
Amane-kun, I've never thought 
of you as a burden.
أماني-كن، لم أعتبرك عبئاً يوماً
Ich habe dich nie als Bürde betrachtet.
Je ne t’ai jamais considéré
comme un fardeau.
Ma io non ti ho mai considerato un peso.
Amane-kun, nunca pensei em você
como um trabalho extra.
Ты для меня не обуза, Аманэ.
