"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."
When it is Roswaal-sama's clothing, 
my priority is to be careful,
لو كان لِباساً لروزوال-ساما فالاعتناء به

Mi prioridad es cuidar
la ropa del señor Roswaal,
J’aurais été soigneuse avec les habits
de maître Roswaal, mais pour toi…
Quando lavoro sui vestiti del nobile Roswaal
ci metto sempre il massimo impegno,
Quando é uma vestimenta para o Roswaal-sama,
eu tomo bastante cuidado.
Для его светлости я бы не спешила 
и работала на совесть, но раз одежда твоя…
