The heroine has been singing on the pedestrian street with her single mother since she was a child, and she grew up listening to the old song "I Only Care About You". Because of a coin dropped by the young male protagonist while singing on a rainy night, she was treated as an "equal singer" instead of an object of pity for the first time. This moment became the only glimmer of light in her gloomy childhood, and also quietly shaped her understanding of "music and kindness".
Ten years later, she broke into the mainstream music scene with her talent and hard work; the male protagonist became a hot but hidden gold medal producer. The two reunited on a gorgeous stage and a ruthless capital game. However, under multiple pressures such as the truth about their mother's death, company control, and the split between their old benefactors, they were separated and confronted again and again. Finally, in the re-performance of "I Only Care About You", they completed their farewell to the past, their acceptance of themselves, and their mutual fulfillment.
