So, I'm looking for a game I played months ago. The MC has a wealthy girlfriend who has several siblings, a mother, and an aunt. One sister can't stand the MC because she thinks he's only interested in her money. This sister is engaged or married to a guy who is only after the family's power and money. I remember that they visited the family, I think it was a beach house, and the girlfriend had to travel for a business meeting. The MC is allowed to hook up with other people, but only if he tells his girlfriend. I hope someone can help me with this, thank you in advance.
