This is a romantic encounter that begins with "love at first sight", but goes deeper than a "long-planned" fateful reincarnation. When Lin Zhi, a young girl full of energy, met Jiang Chen, a top student known as the flower of the mountain, she thought it was a coincidence arranged by God. It wasn't until later that she understood that all seemingly accidental encounters were the inevitable result of another person's efforts and efforts spanning time. The chemical reaction between them: it was Lin Zhi's sunshine that illuminated Jiang Chen's inner loneliness; and Jiang Chen's calmness also filled Lin Zhi's lack of sense of security. This extreme complementarity of personalities is the most touching source of tension in the story.
