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, you always 
look so happy when you're eating.
أماني-كن، دائماً ما تبدو سعيداً عندما تأكل
Du siehst beim Essen immer
wahnsinnig glücklich aus.
Amane, siempre que comes pareces feliz.
Amane, siempre que comes pareces feliz.
Quand tu manges,
tu as vraiment l’air heureux.
Hai sempre un'aria così felice
 dopo aver mangiato.
Amane-kun, você sempre parece
tão feliz quando está comendo.
Ты всегда такой счастливый, 
когда ешь, Аманэ.
