18+ ghost webtoon?

So..I really really have been looking for this one webtoon/manhwa that i genuinely forgot the name of. And earliwr this year when mangago reset everyones account i obviously lost the info. I don’t remember the names so we will do boy a and girl a (obviously themain chatacters.)

Some help to help confirm it may be the manhwa/webtoon:

-colored webtoon
-black haired boy mc
-when they have sex he can see the ghost or something (maybe a power/essence) but he sees something YELLOW inside of girl a (hes able to see this cus hes an exorcist or whatever)
-in the webtoon they try to get boy a’s ability back to have emotions from the ghost in boy a.
This is one of the main things they try to aim gor in the webtoon

So this webtoon is 18+, its a smut. Andits also a mix of supernatural/ghost/apparition.

Its kind of a niche because i remember atleast when i read it half a year ago, there we’re lowkey like under 5k reads.

So i dont really remember the plot. However i do know that someone is possesed by a ghost. Either girl a or boy a. I believe boy a? But what i do know is boy a has a power, and its to exorcise people. However, he isn’t able to feel any emotions when exorcising. This is VERY important.

And this becomes very hard. Because all the people he wants to exorcise- they obviously want someone with emotion and to see that their exorcist- cares. That its true tha the exorcist wants whatever is possessing them- gone.

But hes literally incapable of showing that. Over time hes overcome this, and mastered the art of faking smiles and emotions.

But he realizes, whe he meets girl a (which was a one night stand but obviously
Quickly changed) that his power or something? (I may be straying off?) increases when he has sex with girl a? (omg i think im wrong idk). OR maybe that he can feel emotions with girl a. OR that when he has sex with girl a, he can see the ghost that possessed girl a, dying down… (this is where im lost cus my memory is blurry)

But i really really wanna find this smut webtoon but i cant. Cus they deadass have such good sex help me anyone pls…
