Gu Yanshen, the president of Gushi Technology, got stuck when he was developing an "emotional brain-computer interface" - the device could not capture "true love brain waves" until neurologist Su Nian came to do a clinical test: when her fingertips touched the device, a "99% matching degree" popped up on the screen. Gu Yanshen discovered that as long as she and Su Nian were in the same room, the stability of the device soared. It turns out that the ancestors of the Gu family left behind the secret that "true love brain waves can activate special technology", and Su Nian is the key. At first, Gu Yanshen wanted to "borrow" her brainwaves, but he became interested when she helped the patient use an interface to relieve his depression and accompanied him to fight against his second uncle who was trying to steal the child. The second uncle secretly tampered with the device data to frame Gu Yanshen. At the critical moment, Su Nian held his hand and said, "I believe you." The love brainwaves between the two actually caused the device to reversely track and find evidence of the tampering. In the end, Gu Yanshen kept the company, and Su Nian also relied on the interface to help more patients, growing from an ordinary doctor to a department director. In daily life, Gu Yanshen uses the interface to "sneakly read" Su Nian's thoughts, but is always made red-faced by her "complaint brainwaves" and burst into laughter.
