Looking For Yaoi Manga

Hi I was recently reading this yaoi Manga but forgot to add it to my lists
So I try to describe it as accurate as I can

The main character works for a company and on a business "party" he accidentally peeks on a very popular and successful business man beeing involved in sexual activities with several other business men.
They meet again and the successful guy knows that the main saw him and makes a contract for his company in exchange for sex
They start a sexual relationship and become business partners basically

Sorry If it's a bit mixed up but it's a quite popular manga so maybe you know it

I'm looking for manga/webtoon/novel that is similar to At The End Of The Road (webtoon) and Kill The Lights (novel).

The main plot is basically the MC died and woke up in another person's body. The ML then, through some interactions, recognizes the MC even with his different appearance. (Because the ML has always love the MC.)

No Quick Transmigration please, as I've read most of them or the new ones have too little chapters for me to get into it.

Thank you!

Someone posted on fb this manhwa but they didn't know the sauce. I've been searching for so long because I'm interested but no luck. The picture that been posted is a guy that have this cow features on him. He got this horn on his head and a guy is offering a coffee? to him and asking him if he got milk(Got milk?). Please if anyone have read this give me title or the link. Thank you.
