I've lost my waistcoat!! Grell x M!Reader

Otto von Nachtraben, a man cast out by his noble German family found his way to England in the early 1800s, becoming an actor in Henley, later in London until one day he was discovered to be in a relationship with a fellow actor. Facing the death penalty, Otto was discovered hanging in his cell the day before the execution. Punished with collecting souls, Otto returns as a reaper, getting caught up in the likes of Ciel Phantomhive and Sebastian Michaelis. However, the waistcoat his lover made for him seemed to have gone missing after Otto changed into his reaper uniform and a certain red-haired reaper is happy to assist in the human world if it gives her a chance to see her Bassy and maybe realise that there's a certain someone who finds interest in her too.
