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.
You should have accepted your 
need to rest from the start.
كان ينبغي أن تقبلي حاجتكِ للرّاحة منذ البداية
Höchstens, wenn du dich
direkt brav ins Bett legst.
Solo si te rindes y te vas a descansar.
Solo si te rindes y te vas a descansar.
Non, parce que t’en fais
qu’à ta tête.
Così impari
a non metterti a letto fin da subito.
...mas só se você desistir
agora e descansar.
Только если ты сама
согласишься лечь отдыхать.
