This is a miraculous love story that spans life, death, time and space.
Lin Yu is an ordinary high school student who traveled to ancient times in an accident and met Fusu. The two fell in love at first sight and made a love agreement forever. However, their love is destined to be difficult to realize in this world - Lin Yu must return to modern times, and meet and part ways again and again in different generations for the rest of his life.
When Lin Yu returned to modern times to continue his studies, everything seemed to be just a dream. However, an ancient book and a new student Chen Si who looked like Fusu brought that memory back to the world. Lin Yu realized that although the love of life and death will not be realized in this world, their souls will never be separated in the corner of life and death.
Chen Si comes and goes like a passer-by, and life is short like a fleeting moment. The only place where Lin Yu can stay with Fusu is in the promises and memories of life after life. There, time loses its meaning and life and death turn into nothingness. They loved each other all their lives and never missed each other.
This is a magical and bizarre story about life and death, making people think about the ultimate value and meaning of life. Love transcends everything and becomes eternity. Two souls find their belongings in life after life, and finally have love forever. Maybe life is short and fleeting, but love can transcend life and death and spread forever in memories and emotions.
Life has the pain of separation and death, but sincere love from life to life will allow two people to have eternity beyond life and death. This is the most magical and touching encounter and reunion, a beautiful legend that will inspire more people to pursue the ultimate meaning of life and the secret garden.
