In his previous life, Lin Yu was blocked by capital for ten years, and his ambitions had nowhere to display. After being reborn, he became a single father, struggling to survive with his six-year-old daughter. During the kindergarten performance, he was pushed onto the finale stage with no accompaniment or rehearsal, only a guitar and full of unwillingness. A song made the whole audience cry, and also made everyone remember this man who held the guitar and sang softly - he would never let anyone step on his head again in this life.
