What do you think of this idea for a book? Please Answer!! Easy 10 Points!!!?

Here is my idea. Okay, so the main character's name is Corley and she is 37. Her sisters are Miranda (44), Georgia (39), and Lily (26). Miranda and Georgia are married but Corley has yet to settle down because she cant find "the one". Corley goes on at least three dates a week and prefers to have casual sex with her gardner. On the day of her youngest sister Lily's wedding she realizes that she is the only one unmarried. Her sisters talk to her later about how she needs to find a man. Corley doesnt think it is a big deal. She goes to tell her best guy friend, Rich who is a bartender, and he agrees with her sisters. Corley meets a man at an art class one night named Kieran. They start to date. Kieran is very loud and nobody likes him. In the end they find out Kieran was having an affair with Georgia and Corley gets married to Rich.
