Okay, let's get deep for a second because this book is way more layered than it appears on the surface.
The central symbol is obviously pregnancy—but not in the traditional romantic way. Here, pregnancy is LEVERAGE. Jiang Sesè explicitly thinks: "With a child, she would have leverage. A-Huai loved her, cared for her—and now, with a child in the picture, he would surely divorce Lu Zhenzhu immediately." This isn't about creating life; it's about creating a hostage situation. The baby is a tool, a bargaining chip, a weapon.
Then there's the hospital test result. "The top one is your test result. The one below is the one you wanted." Jiang Sesè tears up the unwanted result without hesitation. That's symbolic of her entire approach to life—discarding anything that doesn't serve her purpose. She's not mourning a failed test; she's eliminating obstacles.
The spicy fish is another symbol I can't stop thinking about. It's supposed to be a treat—Lu Zhenzhu "had always liked spicy food." But it triggers Jiang Sesè's nausea. The fish represents everything Lu Zhenzhu has that Jiang Sesè can't touch: Gu Huai's genuine care, his attention to her preferences, their shared history. Jiang Sesè literally can't stomach it because her pregnancy makes her physically incompatible with that world now.
And the jacket scene! Gu Huai draping his suit jacket over Lu Zhenzhu's knees. It's a gesture of care, yes, but symbolically it's about protection, possession, marking territory. He's covering her, claiming her, while Jiang Sesè watches from the outside. The jacket becomes this symbol of the marriage Jiang Sesè wants to destroy but can't access.
The most devastating symbol though is the pet metaphor. When Jiang Sesè realizes Gu Huai's feelings for Lu Zhenzhu, she thinks: "Even a pet dog or cat, when kept long enough, would be hard to abandon. Lu Zhenzhu was just a pet Gu Huai kept for comfort—there might be affection, but surely it couldn't compare to what he felt for her." She's comparing her rival to an animal, trying to diminish her, but the irony is that Jiang Sesè sees herself as Gu Huai's true love while treating human beings like objects to be managed.
The title of chapter 18—"Get Rid of the Child"—is brutal in its clinical detachment. It's not "abort" or "miscarry" or any softer language. It's "get rid of"—like disposing of trash. That's Gu Huai's voice, that's his worldview: children are things to be managed, women are roles to be filled, love is a transaction.
And Chen Hang's offer at the end—"I might not marry a divorced woman, but I can certainly keep you well-provided for"—reduces Lu Zhenzhu to exactly what Jiang Sesè fears becoming: a kept pet. The circle completes itself.
