"After being badly wounded by Elsa, Subaru somehow survived and awoke in the mansion of Margrave Mathers, in the Kingdom of Lugunica.

Subaru now lives and works in Roswaal's mansion, working with Ram and Rem, and finally getting Emilia to agree to a date with him. But the day of their promised date never comes as Subaru keeps going back to the day he first awoke in the mansion. He's confused at the thought that he Returned by Death despite having no memory of experiencing anything deadly, but he's determined to repeat his previous actions up to the point of fulfilling his promise with Emilia."
Huh? Oh, I'm just a bit groggy 
from oversleeping.
أنا مترنّحٌ قليلاً فقط من الإسهابِ في النّوم
Na ja, ich bin nur ein bisschen träge,
weil ich zu viel geschlafen hab.
Eh? Oh, sono solo un po' intontito.
Ho dormito troppo.
Hã? Não, eu só estou um 
pouco zonzo de tanto dormir.
А? Ну, немного ослабел от долгого сна.
