Sai Mo, the lord of Yue City, and Tong Huan, the princess of Yan State, have been in love for two generations. They cannot stay together if they love each other, and they cannot love each other if they stay together. There is a gap in the world, but it cannot bridge life and death. Maybe Tong Huan has always been a little bell, maybe she has never been.
Intention: Love bravely, choose between regret and sadness
