Jiang Wanqing's golden finger is the "emotional pause button": whenever she drinks an iced American, she can temporarily mute the emotional fluctuations of those around her. She can clearly see other people's emotions - such as the scoring gaze in the eyes of her blind date, the perfunctory look behind the fake smile of her colleagues, and the anxiety behind the concern of relatives, but these emotions can no longer affect her psychological rhythm. This ability only works for her, like an invisible shield, allowing her to stay awake and humorous in the storm of marriage. She doesn't avoid marriage, she just refuses to be coerced by her emotions. As the plot progresses, she gradually switches from "passive defense" to "active insight". By observing other people's emotional blind spots, she feeds her own growth and quietly changes her understanding of intimate relationships. The ability is simple but has boundaries - it can only block emotional interference, cannot read minds or control others, and is limited to three times a day, triggered by the Ice American Style. She is teasing the world amidst the urban fireworks while getting closer to true love.
