Trying to remember a certain manhwa

Please help me find this manhwa that was a hoax that set in European noble setting. The bottom is a mercenary but he gets caught by a noble (ml) whose been spying on him doing the deed. Their relationship is forced one sided on the part of the top. All I remember is that the noble ml was BIG into Bdsm and the MC was a beefy bottom lol. Thanks for the help in advance!! (づ￣ ³￣)づ
