Lin Xu, a talented but scarred voice actor, was invited to record a video for a psychotherapist because of his unique "healing voice". In the process, he seemed to be having a conversation with a lonely soul who could speak concrete words. He fell hopelessly in love with the "her" he had never met at the other end of the audio and built a perfect spiritual home in the sound world. At the same time, Shen Xing, a passionate female psychologist, boldly pursued him, doing everything he wanted and making her feel When it came to his soul mate in reality, when Lin Xu decided to confess to her on the other side of the APP and rejected Shen Xing that night, he was shocked to discover that Shen Xing was the user behind the voice. When love becomes a designed echo, how can we tell the difference? The throbbing in my heart is the heartbeat of fate and truth. Or is it a sound wave carefully designed by someone else?
