Innocent 4: Alicia - The League of Worldly Wise Innocents, #4

Alicia Wu hates her hymen. She's not in a rush to break it, but she wishes everybody would quit making such a fuss about it. Her parents. Her pre-fiance's parents. Him, though he claims it's not a dealbreaker. That small piece of thin skin is not important to her. It's not like she even believes in love. She is ready for marriage, though her accountant nerd pre-fiance underwhelms her. His father is a wealthy businessman.
Having worked hard in her parents' chop suey joint since a child, Alicia is ready to join the country club set and spend the rest of her life playing tennis and golf, in between having the grandchildren her future in-laws want. After the families finish exchanging letters, they must hire an astrologer to choose an auspicious day for the official engagement celebration. And, after that, a lucky weekend day on which they can hire a suitable hall.
Then, at a college party, Alicia meets Bran. He delivers the pizza. She delivers the fried rice and egg rolls. Blonde. White. Blue-eyed. A fan of Goth rock. Like Alicia, Bran doesn't believe in love, he just wants to have a good time. And, a victim of the Great Recession, he's given up his college ambition, and just wants to remain a pizza delivery dude for the rest of his life. Alicia's parents automatically hate him.
So why does Alicia feel compelled to offer her unbroken hymen to Bran?
