help me find this bl manhwa pls

it was fairly new, about young black haired shaman. he has a best friend or relative who works with him. idk if the shaman thing waa scam or if he was actually good at it or it was a mix of both. i dont remember how but he gets caught up with a gang lewder who is highly superstitious and i think he was afraid of getting killed so he tells the leader only he can protect him with his shaman powers? or he tells him that his powers can only be activated by sleeping with him to scare him off but the gang leader really does sleep him and from where i felt off he was stuck in a room. the gang leaders cousin or somwthing who's is rival as heir visited him in secret a few times. it wasnt even in the middle of the story when i started reading a few months ago and updated weekly. when i last read a some months ago, maybe 5-7months ago i thinknit had 15 chapters to maybe 30 chapters. it had really good art and the artist was great at glowing effects
