hey guys, i'm looking for a manhwa i don't remember the name but i remember a bit of the story.

So, I remember that the story is a love triangle between a girl, her childhood friend and a guy if I'm not mistaken, he's the CEO of a company and he's also part of a mafia (he's the boss)
the girl is a lawyer (and i think shes sort of a genius) and she work at the company of the mafia guy , I remember she was having economic difficulties and her grandfather was hospitalized, I think she even signed a contract with the mafia guy in exchange for him paying the hospitalized grandfather's expenses and she would be his wife.
I don't remember much of the story, but this girl became the mafia guy's lover and that same guy also abused her, so one of the guys who works with the mafia guy let her run away and she took refuge at her best friend's house.

Its all i remember for now, if someone could help me find this manhwa please, it would be so awesome. 🙂
