I am looking for bdsm related mangas, I’m open to anything really, I just can’t get over the bonus chapters of bj Alex and now I wanna read something like that :( pls help me out

trying to remember the isekai one where the girl has drill hair and her and her butler guy that's low-key in love with her are trying to bully the heroine and get her with the ml but she ends up being nice in a way.. like the heroine has the ugly dress from the game so they help her fix it up.

Guys, please help me. Its this one manga about a guy(Bottom) who works at a company but as a spy or something to leak the company’s information. And then the top is the owner/CEO of the company who is a foreigner. I kinda forgot how the story goes thoo :(

Looking for a manga about how this one omega thought he was alpha or at least beta, then turns out he is omega. He tries to hide it from his friends but his soulmate is one of the dudes from the friend group and he makes the omega go in a heat but then his childhood friend ends up biting him and making the omega his in front of the rest of the friend group on top of a school roof. I think they thought that they (the childhood friend and omega) were soulmates but remember it was someone else from the friend group. But years later this one other omega that works in a restaurant goes into heat because the childhood friend is his actual soulmate and not the others!
^^^
that part was so sad to me because the omega starts yelling and crying “that’s my soulmate!!” (ᗒᗣᗕ)՞(;´༎ٹ༎`)
