There are some really interesting symbolic layers in this passage that I think deserve attention.
The gardenia scent keeps coming up. When Zhou Guchuan gets in the car, "a refreshing scent filled the air, enveloping the entire car with his presence." And then when they hug: "Almost the moment the woman approached, the scent of gardenia filled his nostrils." Gardenias are interesting because they're associated with both purity and sensuality—they have this heady, almost intoxicating fragrance. It's a scent that demands attention. And Yin Lan's reaction to it—"her pores were being invaded"—suggests that Zhou Guchuan's presence is something she can't resist, even when she's trying to.
The horror movie is also symbolic on multiple levels. Yin Lan is literally watching a film about darkness, fear, and hidden dangers while sitting in a dark theater with a man she's trying not to fall for. The ghosts on screen are fake, as Zhou Guchuan points out, but the real fears she's dealing with are internal. And the fact that they're the only two people in the theater—isolated, alone, in the dark—creates a pressure-cooker environment where their relationship has to move forward or break.
Then there's the recurring motif of light and darkness. Yin Lan only dares to watch the movie during "daytime scenes" and covers her eyes at night. Zhou Guchuan, meanwhile, is described as standing "against the light" at the airport, looking almost celebrity-like. The mysterious chairman nobody has ever seen represents someone who operates in literal and figurative darkness. And Yin Lan's past life trauma is something she keeps in the shadows, only surfacing when she reminds herself not to get hurt again.
The island setting itself is symbolic—a place removed from normal life, where social hierarchies and past identities don't apply. It's a blank slate, which is exactly what both characters need: Yin Lan to figure out if she can trust again, and Zhou Guchuan to show her who he really is without his family's wealth as a crutch.
