Looking for Bl

I remember reading an omegaverse bl where it was AlphaxAlpha, one was an accountant and the other was of noble blood. The accountant married an omega that looked similar to the noble alpha, and then the noble alpha got jealous and tried to pay some ppl to attack the omega. The omega ended up dying, and the noble Alpha basically “repented” for like… years, and then ended up in a cottage on his old estate (now owned by the accountant) and I won’t say the rest in case of spoilers.
