chicken

basically i remember 2 years ago reading a story about a priest(or detective) guy with blonde hair and a middle part(?) and red eyes and he had a white coat I think. People were also wondering if it was gonna be a bl or not. Also I think the story had something to do with vampires but I am not sure. The artstyle was in black and white and I think the priest/detective had a sidekick. for the life of me I couldn't find anything online so im shooting my shot here
