Lin Wan, a former Chinese, traveled through time and space as a 16-year-old Korean trainee Han Yoo-jin. With modern music aesthetics and originality, she counterattacked from a trainee to the world's top female soloist in the Korean entertainment industry. During this period, she met the stage king and privately introverted BigBang leader Quan Zhiyong (GD) because of musical resonance. She went through the stages of dormancy as a trainee, rise in debut, separation in the service, reunion after discharge, and overseas peak, etc., With the "two-way redemption of the introverted soul" As the core, the bond of "music drives love, and love helps two-way career achievements" is staged in the real Korean entertainment background (the peak of the second-generation group, the epidemic, YG turmoil, etc.), And finally the love affair is made public and the love and career are fulfilled.
