Please help me find this BL manhwa

guys can you help me find this BL manhwa. i only read 1 chapter of it on social media a long time ago so im sorry for my description since i only remember a smut scene. and since it was a long time ago i dont remember how they looked there was this smut scene where the bottom decides to do sth to make the top feel good, so after researching, he gives him a handjob and plays a bit with the Top's ass with only his finger i know there are too many BLs like that but there are not many where the bottom does that to the top's ass . im really sorry it was embarrassing even for me to describe a smut scene, but the fact that i can't remember what manhwa it was is getting on my nerves. i feel like a pervert for only remembering that scene, but i think that was the only scene that was shown , I tried to ask about it before but no one could find it, so I thought i’d try one last time, At this point i don’t give a damn even if I can’t read the manhwa but all i care about is the frustration of not remembering something for a long time even tho it’s on the tip of my tongue and it’s been about a year and I can’t forget the frustration of not being able to remember.
Edit: I remember the top really enjoyed the bottom doing that.
