The ancient town of Qingxi has preserved secret records of patterns for thousands of years, hiding the secrets of marriage passed down from generation to generation. Su Wantang was good at depicting patterns of flowers and birds since childhood, and Lu Xingci was deeply involved in the context of ancient books. The two met for the first time in Taoxiang and stayed together in the academy day and night. They use candies to convey their hearts, lotuses to express their feelings, patterns to hide their love, and all the heartbeats of the four seasons are captured in words. Make good friends along the way, receive advice from the elders, unlock the secrets of marriage in the ancient town step by step, and see clearly the destined bond between each other. From ignorance and temptation to private determination, from keeping tokens to making alliances with lanterns, they stay with each other year after year, and love each other step by step, so that the fate of three lives hidden in the lines will finally blossom in the world of fireworks.
