"What we were told by their descendants (主角家族後人) was, Don’t forget this, that Ernest and Mollie were in love. Why the hell did she stay? Not why did she stay with him? How did she stay with him? Why one person stays with another, we don’t know. “How” is another issue, another way into the story. The “how” is deception, self-deception; the “how” is love stronger than what she dares think he is doing. So this was a coverup, and yet she trusted." https://www.newyorker.com/culture/the-front-row/martin-scorsese-on-making-killers-of-the-flower-moon
