was it like an officer MC with dark hair + green eyes, who was introduced to a new private detective or someone who was blonde, and their past involved a demon or smth killing them in an orphanage? and the devil was involved and possessed the blondie? and there was an ongoing investigation about a series of strange deaths linked to devils and stuff?
and like the artist/writer of that manhwa made this other story that started with a "p" or something, the two male leads had a strong bromance and they had to go across the world to find certain disasters/artifacts or smth to stop the end of the world. MC in that one had insanely bad luck, dark hair, greenish eyes, and the other ML was blonde.
Looking for a BL with like a reincarnation theme ? I think the bottom betrayed the top in a past life and killed him or something, I think that’s how the first chapter started
