Su Wan and Lu Chenyuan used to be each other's most beloved beings when they were young, but due to a sudden separation and a strange misunderstanding, they regretfully missed each other and severed all contact. Eight years passed quickly, and Su Wan became an independent and tenacious designer, living a stable life in her own small world, thinking that the past had long been buried in her heart. Until one rainy night, the two unexpectedly met again. Now Lu Chenyuan was a powerful, calm and restrained president of the group. When he appeared in her world again, he got closer step by step, unwilling to let go easily. The misunderstandings in the past are gradually solved, and the thoughts that have been sealed for many years are resurrected. Those deep feelings and concerns buried by time have never really dissipated. Going round and round, after years of baptism, this heartbeat that has been delayed for many years finally transcends time and arrives tenderly, allowing two people who love each other to regain the courage to rush to each other after missing each other.
