There's a moment in this chapter that I can't stop thinking about. After Xia Zhi finally takes in all four children, she comes to what she herself calls a "tragic realization": all four of them look exactly like Wen Shihan. Not a single one resembles her. As she puts it, "It was as if she had merely delivered them, and once the delivery was done, she was no longer needed."
On the surface, this is just a funny, self-deprecating thought. But underneath? It's the entire thematic question of this story. Who does Xia Zhi belong to in this future? She's the mother, the wife, the center of this family photograph—but genetically, visibly, she's erased. She's the vessel, not the source. And yet the children's love for her is undeniable. Wen Yi clings to her neck. Wen Le demands hugs. They don't care that she doesn't look like them.
The marriage certificate date—September 9, only three months after the elevator accident—carries similar weight. Nine plus nine. A date that looks like a promise but feels like a collision. The accident that brought them together also nearly killed them. Love and danger as twin forces.
And then there's Wen Shihan's smile. Xia Zhi notes that she had never seen him smile before, that he was always serious and intimidating. But in the photo, in that white shirt, he looks "quite handsome." The smile that exists only in a future she hasn't lived yet. The theme here is clear: identity is not fixed. The man she feared becomes the man who gently strokes his son's hair. The woman who feels like an impostor becomes the mother four children beg for pinky promises. The question the story keeps asking is: when everything changes, what remains? And the answer, quietly, is love—messy, inconvenient, hot-spring-planning love.
