While all this is happening, Lara Jean’s dad asks his daughters for permission to marry his girlfriend, Trina, who he started dating in the second installment, foreshadowing the perfect setting for a traditional Shakespearean comedy finale — a wedding. As Lara Jean decides to follow her gut instead of her boyfriend and go to UNC, her and Peter’s relationship is tested again when she’s ready to lose her virginity, but he isn’t.
Peter’s mother then asks Lara Jean to break up with her son because he is considering following her to UNC. It’s a twist on high school sweethearts making sacrifices to stay together through college with the boy following the girl, and Lara Jean drunkenly does it. As we know, nothing good happens when drunk, but Lara Jean hadn’t learned to expect that yet.
