NAME PLEASE

I'm trying to find a Yaoi Omegaverse manhwa where the bottom is first an Alpha duke and falls in love with another alpha duke who already has a lover later he orders to kill the top's lover and after that goes bank corrupt and turn out that he is changed into omega.
This guy suffers a lot and after so much time the top take him to his mansion but treats him really bad.....
I'm trying to find this but I can't remember it's name nor the character's names if you guys know it then please tell me.
