In the future world, the virtual idol industry is highly developed, but the worship of technology has led to the scarcity of real emotions. Top game original artist Su Nian (socially fearful, whose characters are full of emotion) unexpectedly became popular because of his design of the virtual character "Voice of the Stars", but due to his lack of sociability, the project fell into an operational crisis. The former virtual singer Lu Chen (who was outdated and hated hypocritical commercial performances) fell from the altar due to technological iteration, but he has the purest musical talent and stage control. In order to save the project and obtain Lu Chen's original music authorization, Su Nian and Lu Chen signed a "pretend to be a couple" agreement and jointly participated in the phenomenal holographic love variety show "Overclocking Heartbeat". From the initial awkward business and mutual dissatisfaction, to forced cooperation and unexpected events (such as double holographic stage accident rescue, joint response to online violence, rescuing fans suffering from emotional disorders, etc.), They gradually see each other's true nature hidden under the agreement - her fear and his pride, her creativity and his perseverance. When the agreement expires and the entire network presses for marriage, and the two people's respective crises (the project is threatened by a large company and Lu Chen faces being completely replaced by technology) break out at the same time, they must make the final choice between "commercial performance" and "true self" and lead the team to redefine the values of "virtual" and "real" with an ultimate concert that combines real emotions and top technology.
