One thunderstorm night, a mysterious "Emotional Hourglass" APP unexpectedly appeared on Xia Zhixing's phone. It allows her to "see" other people's emotions, and can even use "resonance points" to fine-tune the flow of emotions! From the test anxiety of her roommate who was afraid of the exam, to the hidden fatigue and irritability of Internet cafe owner Gu Shiyu, Hourglass APP has become a new window for her to understand the world. She carefully used her golden fingers to help her classmates solve campus crises, resolve rumors and malicious competition in Internet cafes, and gradually became a "little lucky star" in the eyes of her classmates. And the Internet cafe owner Gu Shiyu, who looked cold and distant but was actually gentle and considerate, gradually let go of his guard with her gentle "assist", and his exclusive "goodwill hourglass" for her emerged from his emotional hourglass. However, as the APP was upgraded, higher-dimensional warnings quietly emerged, and Gu Shiyu's emotional hourglass also revealed a "secret" background. Is this special golden finger a booster for her sweet love, or does it hide a huge unknown risk? Can Xia Zhixing heal others while also reaping his own true love and growth? This is a story about hourglass, emotions, growth and love with sweet pets. We look forward to your reading!
