From the interview: Newsweek: But there was so much adultery in the book! Everyone was sleeping around and breaking up with each other. It’s sort of a dim view of love.
Min Jin Lee: Love is an absolutely tantalizing, beautiful thing. And yet, it is profoundly disappointing, too. I think adultery is a wonderful metaphor of betrayal. Sex is this intimate act between two people. In its highest form, we believe that it’s to be held sacred between two people who love each other. And that’s the reason why adultery always wounds us so much. But, if you take that as a metaphor, you can have adultery in friendship, you can have adultery in any intimate relationship.
