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.
Are you going to overdo it 
while you let me just slack off?
هل ستضغطين على نفسكِ بينما تدعينني أتكاسل؟
Mich zwingst du, mich auszukurieren,
und du machst weiter, als wäre nichts?
¿Vas a seguir esforzándote
mientras me dices que me relaje?
¿Vas a seguir esforzándote
mientras me dices que me relaje?
Donc, tu me demandes de me reposer,
alors que toi, tu te laisses aller ?
Vuoi ridurti allo sfinimento 
mentre io me ne sto qui a non far niente?
Me fez descansar tanto,
mas vai relaxar com você mesma?
Меня отправляла лежать, 
а сама остаёшься на ногах?
