There's something deeply symbolic about the stairwell scene that I can't stop thinking about. Stairs — they're liminal spaces, right? You're neither here nor there. You're in between. And Haitang uses that in-between space to turn her enemy's aggression against herself. Zhang Xiaoxue wanted to push Haitang down, literally and figuratively. But instead, she falls on her own. The stairs become a mirror — they reflect back exactly what you put into them. This connects to the bigger theme of the novel: what goes around comes around. Haitang has lived this life before. She knows what betrayal looks like, she knows what malice feels like. In her past life, she may have been the one who fell. But this time, she's the one who dodges. And Wen Li — oh god, Wen Li. The girl who panics when she sees Haitang, who hides her jealousy and hatred behind lowered eyes. She's another piece of this puzzle, another person from Haitang's past whose true nature is starting to show. The author keeps returning to this idea of hidden faces — Zhang Xiaoxue's 'panicked mask,' Wen Li hiding her emotions, Haitang performing vulnerability while calculating everything. Nobody in this story is what they appear to be on the surface. Even the friendly deskmate Mingyue, who seems genuinely warm, exists in a world where everyone is playing a role. The deeper question the novel is asking is: in a world full of people wearing masks, how do you tell who's real? And Haitang's answer, so far, is to use her past-life knowledge as a compass — not to trust anyone blindly, but to read the cracks in their performances.
