In the memory, an immature boy tightly hugged her who was afraid of the dark in the dark night, promising her long-term companionship and never leaving her; in the memory, a smiling young man gently stroked her temple hair with his slender fingers, promising her a long life of worry-free hairpins; in the memory, a heroic young man stood hand in hand with her in the majestic Huangji Palace, promising her to share the country, life and death. What he promised was more than a lifetime of love? It is the unforgettable feeling that is firm in reincarnation!
