Someone help me find this BL:

It is a supernatural BL and they fight ghost or something. The last time I saw the cover, both of them were standing in a red door something. The ML has black hair. They start out as companions fighting ghost and then they fall in love and I think it’s already completed.

Someone please help me, I searched my account for nearly an hour trying to find it, but I think mangago removed it again in my bookmark
