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.
Would I make fun of 
someone who's trying so hard?
وهل أسخر من شخص يحاول بجدّ؟
Pensi davvero che riderei di una persona 
che s'impegna così tanto?
Eu tiraria sarro de alguém
que está se esforçando tanto?
Разве я могу потешаться, 
когда ты так стараешься?
