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 just think, you're so cute, it's a 
shame you can't always smile that way.
أقول لنفسي فقط بأنّكِ ظريفة جدّاً لدرجة أنّه من الهدر
ألّا تستطيعين الابتسام هكذا دوماً
eres tan adorable
que no puedo evitar pensarlo.
eres tan adorable
que no puedo evitar pensarlo.
C’est tellement dommage
d’avoir caché ça, jusqu’ici.
l'ho trovato davvero carino, 
è un peccato che tu non sorrida sempre così.
você fica tão bonita que até
parece um desperdício não sorrir.
это было очаровательно.
Тебе стоит улыбаться чаще.
