"Starlight on the Heart" - an extremely sweet love song about the throbbing of youth, running in both directions, growing up together, and finally growing old together. Here there are innocent and ignorant secret loves, passionate and sincere confessions, constant companionship, and complete happiness from school uniforms to wedding dresses, from a world of two to a family of four. Follow the footsteps of Gu Huai and Xu Youran and feel the pure, warm and eternal love like starlight. He was the guiding star in her heart, and she was the warm light that illuminated his cold world. An ultimate sweet love from ignorant heartbeat to a lifelong bond. We meet for the first time in the sea of stars, and the lake in our hearts is slightly turbulent (high school chapter); we meet again in Yungang, and our love grows stronger (college chapter); we hold the starlight in our hands, and the future is promising (workplace marriage chapter); the final chapter: the starlight in the heart shines forever.
